i started playing back when ovenbreak was the only one and it's still my favorite. i didn't care much for cookie wars which i guess isn't even in the app store anymore :/ but i like kingdom ok. not a huge fan of the base building aspect but the story's fun. i'm playing the crumble idle rpg the most right now. i used to be a big afk arena player before i reached the point where f2p becomes mathematically impossible, and crumble scratches that same itch for me. in terms of idle rpgs it's probably one of the best ones i've played.
i've never tried or heard anything about ovensmash, tower of adventures, or puzzle world. are any of those worth playing?
(also i just realized there's something called cookierun classic in the store--omg the nostalgia, i might have to get that one rn)
