I know exactly how you feel - my escape from my usual types of games recently have been older games. 3 games I played recently that I found a lot of fun were:

Bloodrayne
India Jones and the Emperors Tomb
Beyond Good and Evil.

For me it would be Monkey Island.

Actually it already helps just to fire it up and listen to the music... ;-)

Zombie Night Terror
Mixing the Lemmings gameplay with the Zombie theme is an awesome idea and it works incredible well. Trying to kill everybody with these cute, little (but also bloodthirsty) Pixel-Zombies is really fun. Highly recommended!

What the hell are you people doing here reading this post, you should be playing this game!!!!

I found myself looking for such a game today. I played Hotline Miami, it worked.

Sorry, I'm too busy shooting mutants/demons in the face right now. =P

What the hell are you doing at my high school reunion?
