Listed in no particular order:

1) Secret of Mana: This was kinda my first game I really liked as a kid and it was sort of my first foray into rpg's. I loved the weapon and magic system which made all sorts of combinations of attacks possible. The story was merely okay, but it still provides some good stress free fun to this day.

2) Worms Armageddon: something so satisfying about selecting armageddon mode and blowing up the enitre landscape, seeing how few worms survive.

3) Heroes of Might and Magic III: I think this was arguably one of the best might and magic games. It has a pretty simple formula that can keep me engaged for a long strethces of time if I'm not careful.

4) Curse of Monkey Island: the puzzles are fun and the artwork pleases me. Plus the music was great.

5) Call of Duty: One of the few FPS I could really get into. I generally really only liked the single player, because after ever break I took from that game all the hardcore players kept getting too good to play on, but the campaign mode still entertains me.
