Do I'm really into games that features summons, collecting them or gathering characters. I like the variety and what not. So I've played Final fantasy games, suikoden games, pokemon and Golden sun, so I was hoping you guys can suggest games with similar features of gameplay. Any games for DS or PSP would be nice. Thanks
Try out the SMT series, I think both systems have games for them. Personally, the Persona (3 and 2) series for the PSP are pretty top tier. Also, it's near impossible to get all Personas on your first run without a guide.
There's also both Devil Survivor games. (Get Overclocked on the 3DS if you want to play the first one but haven't)
