If MMOs count, Runescape. Although personally I wouldn't count MMOs since they're updated with new content regularly.
Real answer would probably be Serious Sam: The First Encounter. I played it a few days ago for about 10 minutes, while waiting on The First Encounter HD to finish downloading. I bought the Serious Sam Gold Edition pack on Steam for £7.50! I love Steam. My bank card doesn't though.
