Resident Evil 5 is one of my absolute favorite games on the Xbox 360/PS3 so it's cool you have it. Many people don't like Resident Evil 6 but I love it and think it's worth a shot if you find it cheap. Revelations 1 is also on it, but it's coming to PS4 if you'd prefer to get it there. If you don't have Resident Evil 4, that's also on PS2/PS3/Ps4.
Here's a list of what else I recommend (most are multiplatform just a heads up):
Mass Effect Trilogy (You can only get the first game physically if you buy the trilogy edition from what I understand)
Fallout: New Vegas
Grand Theft Auto V
Red Dead Redemption
Tomb Raider (2013)
Saints Row 2
Saints Row: The Third
EX Troopers. VERY import friendly so language, not an issue.
Dungeons & Dragons Mystara. The physical version while in Chinese easy game to play.
Strider 2014. Despite being an import it's fully in English. Comes with a digital copy of Strider 2 on PS1 and Strider Arcade.
3D Dot Game Heroes. Great game that is inspired by NES Zelda games.
Kingdoms of Amalur-Better than Dragon Age IMO
Metal Gear Rising. Metal gear lover or no this is a must-have action game.
Folklore is an underrated forgotten gem.
rain-great Ico like game.
VanQuish. Only the best TPS ever made.
Binary Domain. Only the second best TPS ever.
Zone of the Enders HD Collection. Just play the second game on the disc.
Soldner X-2 Prototype. Really good shmup but only physical on Vita.
Virtua Fighter 5. Best in the series, last in the series.
Darksiders games. M Rated Zelda.
Nier. As a game it has flaws but man it's worth playing.
