I've been closely following the development for all GEM engine games since like 2015. I've been playing the Men of War series since Faces of War.
Call to Arms (DMS)
I was only aware of Call to Arms when a alpha version got put up on a pirate site. The game had been fully crowdfunded and entered early access in 2017 (after closed beta's). Coming from the (pirated) alpha version, some features were just removed for no particular reason. Offline multiplayer over LAN was removed, which was extra terrible as the new online netcode was less stable than before. The game also uses 4K textures, which affects performance even if you don't play in 4K (and even then, the game UI doesn't even scale to 4K). The factions are very balanced but that makes them all play the same. A Toyota pick-up shouldn't be as resistant as a MRAP. You also had to level up to unlock units in multiplayer, which can't be bypassed without changing lobby settings (which don't give XP). The first/third-person Direct Control mode is completely unbalanced (especially against the AI) as there was nothing stopping you from hitting targets beyond the intended maximum range.
Also during the early access period, one of the devlogs did say that modders could revert to the classic Direct Control mode if they wished to do so. The issue was that the code to do so kept breaking so modders had to find workarounds for it. At some point, all the workarounds stopped working. This and other engine regressions at the time caused many modders to stick with Assault Squad 2, effectively making the modding scene dead on arrival.
Call to Arms was fully released in 2018 with a free (multiplayer only with no mod support), paid (mod support and singleplayer) and deluxe editions (more factions and no grind), and a season pass with early-access to the then-missing factions from the roadmap. Many backers and early-supporters were pissed off at this.
The game has had improvements, such as adding a official option for the classic Direct Control mode and a 64-bit engine. But it hasn't caught more attention outside of sales bumps and the multiplayer died. Development has since been sidelined in favor of some new unannounced game.
Call to Arms - Gates of Hell: Ostfront (BWS)
Originally was going to be published by Best Way, using the same engine as Men of War II. In 2019, Best Way dropped Gates of Hell along with their devs' rights to their engine. BWS ended up converting to the (then) much-maligned Call to Arms version of the GEM engine for the game to eventually release in 2021 as Call to Arms - Gates of Hell: Ostfront. That was the reason why until as late as 2023, Gates of Hell required you to own Call to Arms to play it as a standalone DLC. The game launched with some of the same technical shortcomings as regular Call to Arms, such as broken netcode (
drifting tanks and broken artillery towing) and unresponsive AI, as well as being half-baked in some areas. The missions are more varied in comparison to Assault Squad 2. Unlike for Call to Arms, a few modders from Assault Squad 2 did see enough promise in the engine to switch over. Over time, new (and restored) features and content as well as slowly fixing the engine and netcode issues made the active playerbase steadily grow over time. Nowadays, Gates of Hell has a similar median of active players as Assault Squad 2 along with a decent-sized multiplayer size, compared to what it used to be. There's also a few upcoming mods I'm exited for, such as a Star Wars mod and a better modern combat mod.
Men of War II (Best Way)
Originally started as Soldiers: Arena. In 2019, it got picked up by Men of War-series publisher 1C Company and got renamed to Men of War II: Arena.
The original Steam page was later closed. In 2020, a open beta was released in Russia on the 1C Games Launcher. If you weren't in Russia, you could simply use a VPN to play anyway and the game interface was available in English.
As a multiplayer-focused f2p-game, it plays more like a MOBA with a bunch of simplified mechanics. You can only bring a limited amount of units as a deck (similar to Wargame or Steel Division). You use in-game currency to purchase units for your deck. To unlock new units, you use the points you get for finishing matches. In-game, you can only have a few units before hitting a unit limit to encourage teamwork between players. Artillery had no range limit, which made them hard to counter with infantry and tanks as they would often get destroyed before getting close. There was also your standard premium currency to buy premium units, which surprisingly weren't more unbalanced than the non-premium units. There was also a premium subscription that would give you extra points in matches and no artificial currency limit.
Then the devs decided to make higher tier units only useable with a premium subscription. It would have a negligible impact as Arena would shut down in 2021. Besides being limited to some launcher, the game was barely promoted (the only English review video was from
AirshowD, which you might only recognize for recently having a
warplane as a vtuber model).
A few months after Arena shut down, Men of War II got announced on Steam as a paid upcoming new game. 1C was also bought by Tencent and later renamed. After a release date delay, throughout 2022 and early-2023, MoW II actually got marketing outside of a Discord server or some Russian service. The release date was set to September 2023 and much more fans of the series are actually noticing it and getting excited for it. This was especially so after the consecutive letdowns of all the GEM engine games that involved DMS (Call to Arms, Assault Squad 2 - Cold War, and Gates of Hell).
The open beta released in March, and it turned out to be similar to Arena (including the always-online requirement and balancing problems) but without microtransactions and premium subscriptions. Reactions from the older fans were very negative with a bunch of YouTube videos bashing the game for it's more arcade gameplay. In August, the "final" beta releases which added a classic game mode and a realism settings that makes the game play more like the past Men of War games, which was a welcomed addition. But you could only play them with a custom lobby, and there weren't any other significant changes in the beta.
As September rolled around, the game got delayed at the last minute to 2024. It was stated that the game was "feature complete" and just needed "more time to fix bugs".
In the official Discord, there was a lot of whining as well as impatient players blaming the older fans for causing the delay with the added classic mode and demanding the game to be released without it. My favorite part of it is that a Chinese fan translating group got so butthurt over the delay that it dissolved itself (my current about page is the message announcing it).
Another open beta released in November, but the only major changes were adding matchmaking for the classic game mode and new demo missions.
After months of no updates, in March this year,
a update was finally made. With the amount of changes and additions, it doesn't really seem to be a few bugs or "feature complete". Fortunately, they're finally giving artillery limited range so they can't just pick off tanks at very long distances. MoW II will even launch with some official mods from Assault Squad 2, so most modders that have stuck to it are looking forward to it. The game (still) has some engine-level stuff I don't like, such as squads can't be mixed and matched into custom groups. I'm going to get the game when some good mods gets released.
