I play a lot of video games, but here's some cool single player ones I like!
Persona 3 Reload, 4 Golden & 5 Royal
If you like 70-120 hour reading/turn based rpg games, I'd recommend them! (I swear they're great)
Danganronpa 1/2/3
If you can tolerate the writing, they're cool murder mystery games! I haven't played them for a few years tho!
Resident Evil 4 Remake (and other RE games)
I wish leon s kennedy was real
