BIT.TRIP BEAT

BIT.TRIP BEAT is a weird music game. You catch the squares coming along with your breakout rectangle, and hope to god your headache goes away.

Something about this just doesn't hit me the right way. It felt a bit.. boring. At least guitar hero and stuff has graphics, this is just painful.

Orcs Must Die

In Orcs Must Die you fend off waves of attackers from reaching your portal. You use traps, a spear, a crossbow, and a variety of special powers you'll never touch to stop them from advancing. The game is pretty good. I like it, but I was let down by the lack of online beyond leaderboards. This is a game dying for co-op, and it was boring without it. Maybe because it was too easy or something, but it is still a good game. Once you figure out overpowered the arrow walls are though, the game is pretty much over.

Renegade Ops

If you've ever played Smash TV or that special zombie mode in black ops, you've played this. It's a top down shooter where anything you point at dies. You control a tank or car as you drive through the level completing timed objectives. You have infinite ammo with your basic machine gun, and then you can pick up things like a flamethrower, railgun, or rockets. I really like it. Once you get used to driving and shooting at the same time, this game is really good. It's simple and fun.

Just be sure to have a controller on hand. You won't get far using a keyboard.

Audiosurf

Audiosurf is a game where you ride a track while hitting blocks to your mp3s. The technology works most of the time, though things with loud backing tracks won't have as much 'kick' to their main instruments in the game as you would hope. Dubstep = good, Heavy Metal = meh. The game is a bit boring by itself though, and it never really kept me too interested. If you want a casual game to listen to your music, you'll probably be satisfied with Audiosurf. If you're looking for something that will challenge you, you might want to get something that has the music patterns made, rather than generated.

ARMA II

Another game that is like Red Orchestra, Arma 2 takes a long time to get used to the controls, but if you put in the time and effort, it's a really good game. Single player is just a mission mode, but multiplayer is what you'll be playing most of the time. Huge expansive maps and a bunch of people in it is really fun, though in some servers, people get really uppity about what you have to do. All those idiots with the mics may ruin it for some people, but, if you are really committed to getting good at the game, you'll find that Arma 2 has a lot more depth than other shooters such as Call of Duty or Battlefield. 

It just isn't as 'pick-up able'. You seriously need to dump at least 20+ hours into the game to get decent, even if you are a veteran of other shooters.

Saints Row: The Third

I have never played the previous one, which everyone says is superior, but Saints Row the Third on it's own is an amazing game. The storyline actually kept me interested, even if some plot points were shoehorned in, and the sandbox is like GTA 4 on acid. There are a bunch of customization options for your character, your car, and your strongholds. You can upgrade your dude/dudette to have infinite ammo and take no damage from things, but please don't. 

Once I made it so that I couldn't be hurt at all I instantly regretted it because I felt I had no point in continuing to play. I'll prolly make another character again, lol. Get the game. It's great.
