Which game do you reccomend for me?

I like RPG, FPS or strategy games. I like games that are easy to complete and have a great story line. I also like some freedom and side quests. So far, my favorites are S.T.A.L.K.E.R series, Dragon age origins and 2, NFC undercover, Empire earth, Spider-man 3 and League of Legends. Which game should I play, because I completed all of theese many,many times.
