I found this game interesting because it requires you to rewind time(!) to change the outcomes of events to achieve better situations and relationships.

Who cares if it's in development- it's still pretty damn good enough to be treated as a (kind of) full, released game.

It's Sim City 2013, but a whole lot better, on Steam, and not made by money-grabbing scumbags named Electronic Arts.

Sure, it might be a bit overwhelming. But your fervent love of trains and strategy will motivate you to buy it. Unless you don't like trains.

This might not be an actual game, but it is a legitimately fun, long, and interesting read. Yes, this is a book. On the Steam Store.

It's like Risk, but way, way, more complicated. If you are that TBS fanatic, you would buy the game and all DLC on a Steam Sale. I did.

The community is relatively friendly, the game is heavily based on teamwork, and there's always something new to learn to improve your technique.

Duh. It's Gmod. Anything you make has to be well planned (unless you suck). Even the massacres in TTT or Murder have to be thought out first.

It's the first game that brought me into Steam and got me interested in puzzle solving back in 2011. If it weren't for Portal 2, I would not be here.

It's NOT Call of Duty for one. Also, it's methodical, based completely on teamwork, and not all about running around and shooting everything that moves.
