Depends on what you enjoy in games. Cool mechanics, multiplayer interaction, good story, skill-based-gameplay, difficult puzzle solving or what? Also a game's style that you prefer would help give recommendations. Things like retro games, high end graphics, or simple and stylized games.
You have FNAF in your library. And all of these are old games. I had/have GTA 4, BFBC2, CODMW 1/2, CODWOW on the 360 and PS3
Good games on steam : Rocket League, Terraria, Rainbow Six Siege. Just wait for some steam sales and try a few, you can refund afterwards
