Just Get Through [Steam store page]
If you mash together the responsiveness of Super Meat Boy, and the randomness of Spelunky, you get a simple but satisfying randomized platformer.

Deus Ex: Human Revolution - Director's Cut [Steam store page]
While the story is weaker than the original, this FPS-RPG still offers many viable playstyles - and a visually stunning world. And the Director's Cut does a slightly better job of integrating the DLC, although they're still sort of an independent experience.

You also get a few other perks like developer commentaries, although these don't have any visual indicators to show where they are, so they're hard to locate and activate as you're playing. The redesigned boss fights are a nice touch though, and definitely a welcome change compared to the originals.

Costume Quest 2 [Steam store page]
Better environments than CQ1, with the same great characters. The first level is the only bad part, so suffering through that small grind is worth it.

The best choose your own adventure I've played - the choices feel important and engaging, and there are enough features that it doesn't feel like a book

For me this game fell somewhere between Legend of Grimrock and Legend of Grimrock 2 - not quite as good as the open-world of the second game, but Vaporum's voice acting made it more of an engaging experience than the original Grimrock.

Quern - Undying Thoughts [Steam store page]
A really enjoyable first-person puzzle game, with unique challenges and an attractive environment.

You may need a game guide now and then, because the island is expansive, but the majority of the puzzles can be solved by logic rather than guesswork. The exceptions are ones where you may not realize a game mechanic is possible.

Space Pirates and Zombies [Steam store page]
Slow but solid gameplay, though there are some major balance/difficulty issues - and to counteract those you need to grind quite a bit. The graphics are similar to a space RTS, though you have far less units than a normal RTS.

APB Reloaded [Steam store page]
Third-person shooter MMO with odd aiming and repetitive missions. The teams are often completely unbalanced and the mission goals sometimes are as well. Turtling many times wins the match.

The Binding of Isaac [Steam store page]
Decent mechanics but disgusting theme. Enemies can shoot diagonally, you can't. The bad hit-boxes on arrows are frustrating, making yours regularly miss enemies and allowing enemies to occasionally hit you through walls. Made with Flash, low res.

Trine 2: Complete Story [Steam store page]
I didn't enjoy this nearly as much as Trine - it felt like less of a puzzle game and a lot more platformer. The wizard's triangle is gone, and all the characters swim the same now.

PAYDAY The Heist [Steam store page]
A fun co-op experience. The latest AI patch made it much easier to play without all four players being human. Enemy AI still has nearly perfect aim, but the body armor balances nicely if you use cover. You earn new guns and upgrades as you play.

The casting system is reasonably intuitive, and the gameplay itself is as fun as Torchlight, though the heavy corridor feel of the levels detracts a bit. There is a smattering of story and humor throughout, but I wouldn't call it story-driven.

Dead Space 2 [Steam store page]
Much better and scarier than Dead Space, good atmosphere. The camera isn't sluggish and not as close. Combat also seems more responsive, and melee is somewhat possible. The 'Force' is useful, though sometimes the item you're holding disappears.

This feels like a console game - smoothed movement, unchangable (close up) third person perspective. The combat is also poor and frustrating - with guns that seem like they were meant to be used with auto-aim. Melee combat is completely useless.

Left 4 Dead 2 [Steam store page]
Even though Killing Floor doesn't have a story line I still prefer it for co-op fun. This is incredibly easy, and the scripted way the special zombies pop out next to you is annoying unless you have the maps memorized.
