Okay, I really, really, really like this game. For evidence of how much I like this game, look up Rise of the Tenno on the Warframe forums. That's how much I like this game.

Basically, picture a MMOCCGTPS with space ninjas. It's a standard 4-player co-op shooter fare, except with everything perfectly executed; while the controls can take some getting used to, they allow an impressive amount of acrobatics-soon you'll be wallrunning and ziplining and doing crazy Max Payne style dodgerolls (complete with appropriate gunplay)

And getting to the gunplay, it's a remarkably fluid shooter, with a good melee combat component as well. I really enjoy the satisfaction of taking up a shotgun and putting the local Grineer boss in his place, complete with visceral sounds and amazing graphics even on a relatively dated rig. I drool when I see what this looks like on nicer systems.

The game isn't truly an RPG-there's a leveling system, but instead of using skill points like the game used to do, they transitioned in Update 7 to using cards that can be upgraded, which is both awesome and less likely to wind up broken and allowing people to burn through a whole minigun clip in a second. Which is a shame, but probably for the best.

Still, there's an impressive amount of customization, and the really amazing thing is the depth; it's very strategic for a game which essentially amounts to twitch shooting, and for those who really enjoy a challenge or are really awesome there's stealth, complete with appropriate alert systems (fire and alert all the locals, let them hit a security panel and everyone knows where you are) and a bow for stealth takedowns, as well as special melee takedowns which I'm rather unfamiliar with, since the closest I get to stealth is taking out the whole room with a shotgun.

I believe this is my longest recommendation, and there's a good reason for that. Warframe is awesome. Play it.

Oh, and for a F2P game, it's even better because the only things you have to pay for are inventory expansions and cosmetics (though some of the skins do have a minor performance difference, they usually take more than they give, so you're lucky if they're even a sidegrade); you can craft everything else, which actually serves as a great impetus to continue fighting through hordes of foes for the things that you need.

It's actually really, really good for a visceral first-person combat game-not as pretty as Skyrim and there's not terribly much characterization of the protagonist other than "I wanna be a (mage/fighter/dead thief)", but you can kick goblins from rooftops.

Tired of lousy political candidates? Bored with congressional filibustering? Just wanna see it all burn? Well, Fallout 3 provides the opportunity to see wonderful destruction and mayhem all in a remarkably fun game with lots of space to explore. Enjoy all sorts of weapons, friends, and targets as you romp through a Washington DC wasteland.
