Back in 2015 when my roommate wanted to try out the AC series, I gave them my collection of AC games and told them which era each game takes place in. They ended up dropping it and I found out they started with AC3. Told them to at least try out AC2 and they ended up playing all the other games in the series. AC3 truly was a shit game.
I have never completed any of the ARPG games. I could tell Origins had promise with its story but I wasn't a fan of the gameplay. Odyssey annoyed the fuck out of me with health sponge enemies. I briefly enjoyed Valhalla but after like 4-5 territories, I realize it was SUPER fucking bloated though. Hilariously enough, I feel like Valhalla was the one I put the most hours in but made the least amount of progress.
