I don't know, Pekora might play it. I find the original to be quite charming, and the sequel while extremely large and having interface changed didn't charm me quite as much even if it is technically better. Though I think PalWorld might end up being the real problem since it will probably devour the "Building + Cute Monsters" genre for a while and streamers won't even look at Builders 1 until the hype around PalWorld dies down, though I might be wrong.For obvious reasons, the sequel is improved, but imagine playing old entries in a series instead of constantly playing the new thing and moving on. A shocking concept, yes, I know, which means that it's unlikely chuubas are going to stream it either.
Oh, and there's a discount on Builders 1 if you already bought Builders 2, since Steam usually does that with bundles:
DRAGON QUEST BUILDERS + DRAGON QUEST BUILDERS 2 Bundle on Steam
store.steampowered.com
(Just make sure to purchase the bundle instead of the standalone or you won't get the discount for having part 2.)
