1. PlanetSide 2
Funnest and deepest gameplay experience this year.
2. XCOM: Enemy Unknown
A fun romp of a game, not as tactical as the original sadly yet still has a lite-strategy feel to it blended with an nice visual style.
3. Crusader Kings II
A fun game that I found to be a time waster past 20 hours.
4. Sins of a Solar Empire: Rebellion
Though they didn't improve much, the game still shines compared to many other strategy games. RISK in space is how I'd describe it.
5. Farming Simulator 2013
6. FTL: Faster Than Light
