Pretty much much a Super Smash Bros adventure mode video game. Fully customizable characters with up to 4 player co-op play. Unfortunately, no online.

Pure hack-and-slash singleplayer/multiplayer action RPG. One of the best in the genre.

Huge game that gives you guns, grenades, a grappling hook and a communist island nation to do whatever you please with.

Really solid fighter made by a former Capcom dev. No online but a fun as hell party game if you're into fighters.

One of Sega's best games. Very interestingly-executed turn-based strategy with great characters and story.

Randomly generated 2D sidecrolling shooter. You can get tons of loot such as missles that fire out of your butt and the ability to set enemies on fire.

Civ in space. Highly customizable, but no real multiplayer.

It's like Halo meets Rainbow Six in the Star Wars universe. Surprisingly gritty and down-to-earth for a Star Wars game.
