Mainly the gacha and Relink~ I still play the gacha actively, and I've played Relink to hell and back. The gacha is a looong marathon, but it has some incredible stories and there's always something to work towards. Relink is MonHun-like, and you can play it solo as the AI is decently competent.

I see, I kept hearing Relink has a billion grinding which makes me nervous but like I wanna know more lore about this universe since the Fighting game is fun and pretty. Also never played gachas so more a relink looker rn

(I also technically own Versus Rising for Bea, but I didn't have any mutuals who stuck with it so it's been collecting dust in my library)
