Arknights (the original) is the only gatcha I play, because it’s the only one that’s fun for me, has no dumbass weapon banner or rng relics, can be played F2P, where I get all limited characters within 10-70 pulls (almost always F2P, except 2 times where I wasn’t as active, so didn’t have enough pulls), the gameplay is actually good, the story is actually good, art is absolutely beautiful and non toxic playerbase. Hypergryph, the developer “is a music company that made a game” (meme), similar to Warframe. Doesn’t punish for playing casualy.
Now I’m playing Arknights Endfield, currently enjoying it, too early to judge fully.
