9.Attack on Titan tribute game (Yep

)
10.A PS2 Naruto game, I just got really addicted to it
With no particular order:
Dragon Ball Budokai Tenkaichi 3 (PS2 must play if you're a fan)
Any tekken game
Any pokemon game (they're too many and I don't have no favorite XD)
Age of empires II (My first game, holds a special place in my hearth) and age of mythologies
Any mario game (gotta love the classic nintendo)
Those are the ones I can remember right now, any of the first 4 could be the best but I gave then scores based on the time I spent with them and the fun I had, with FFX the story earn it a second place.
Right now, I'm only playing AoTTG and Magic on Cockatrice and sometimes Call of Duty (don't have Battlefield so no hate please)
Sorry for the long post
