Hexcells Plus [Steam store page]
Basically the same as Hexcells, just adding another set of levels - since this game doesn't randomly generate them (unless you buy Hexcells Infinite).

Hexcells Infinite [Steam store page]
While the random-map generation isn't quite as challenging as it should be, I still really enjoy the Hexcells series - they're a modernized Minesweeper.

Minesweeper on steroids - this is a great take on the genre, adding a lot more elements while still keeping a good deductive feel.

Guild of Dungeoneering [Steam store page]
Some of the mechanics are unconventional, but once you learn how to play it properly it's a fun and well balanced dungeon crawler with a twist. It's one of the only rogue-like dungeon crawlers that I actually go back and replay from time to time.

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.

Needs a faster fast forward, and has a few annoyances if you're trying to get Expert achievements - but the normal gameplay is fun and well designed.

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

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.

Beat Hazard [Steam store page]
An interesting mix of music and gaming - enemies generated by songs. Disappointing that they charge extra for multiplayer (DLC - BH Ultra).

This slick looking puzzle game is simple, but enjoyable. As the game progresses you unlock six special abilities and more complex puzzles to go with them. Aside from the simple 'normal' puzzles, there are also 'hard' and 'bonus' levels.

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.
