This takes the setup of a puzzle game and turns it into a panicky action game. After playing enough you get into that wonderful trance-like flow.

Hilarious fighting game. Actually feels really polished. Absolutely fantastic as a party game.

This is right up there with Spelunky as one of the best action roguelikes around. Makes a great pass-the-controller multiplayer game.

A lot of folks criticized this game for not punishing player death, but I still found it charming and fun.

The writing ain't perfect, but the great atmosphere, general weirdness and overall vision make up for it. Simple, solid mechanics help the immersion.

One of the greatest shooters ever is far from 'mindless'. Your brain will be on overdrive most of the time. Few games demand this much spatial awareness

This Diablo-clone seriously beats Diablo at its own game. Crazy deep customization system ensures that you make meaningful decisions continually.

This precursor to BioShock has always been one of my favorite games of all time. Wonderfully creepy, deep mechanics, great sci-fi setting. GET IT.

My favorite sim game. It's a classic, but there's a good chance you might've missed it anyway. Still looks and plays really well to this day.

Hands down THE best GTA-style open world game ever made. Excellent writing and acting, plus really fun brawler-style fighting mechanics. A must-play.
