#38 - Call of Juarez: Bound in Blood (Techland, 2009) - PC (also available on PS3 and X360)
This one right here is my favorite first person shooter of all time. I played this by sheer accident: my brother got it, installed it, I noticed there was a new game and tried it out, just out of curiosity. Then I just couldn't stop. The characters were interesting, the gameplay was exciting, the ability to play as two differente characters (each with their own skills) added some variety... hell, even the plot was entertaining, with an interesting ending. This game was mostly ignored by everyone, and most people seem to think that it's just an okay shooter, nothing special. Maybe I love it so much because I played it expecting nothing? I don't know.
#37: released during the "no gaemz" period of the PS3, not a whole lot of people paid attention to this game when it came out - it wasn't until the sequel was released that people looked back and realized this one was awesome too.
