The Ball

This is a very very boring game. The only reason I got it was for the Potato Sack stuff back when Portal 2 was coming out. I played this once and it was really really.. boring. I don't know what else to say. Nothing interesting happens in the game really, from what I've played at least. There are a many number of other games that you could spend your money on instead. Avoid this one.

DEFCON

A barebones RTS game, DEFCON is extremely easy to get into, but hard to master. Defend your cities from the enemy's nukes and use your own to attack their's. The game plays light ambient music that tries to make you feel emotional and stuff, and a lot of it is artsy. Thought, it stays simple, and out of the way. SAM sites for anti air and for launching nukes, Airports, Aircraft Carriers, and Nuclear Subs. That's it.

It's totally not deep and involved as some.. most other RTS games, but if you want to ravage with a global thermonuclear war, there aren't any other games better to choose from.

Doom 3

While not exactly scary, Doom 3 is a pretty classic FPS by today's standards. No iron sights, no tactical lights (unless you download a mod for it), and not a huge focus on multiplayer. Maybe it's me looking through my nostalgia glasses, but I like Doom 3. Run around murdering demons in a dark, dank, Mars outpost. Fun stuff!
