Europa Universalis IV. By far the best strategy video game currently on the market.
Agreed, though I'm behind one DLC by now. Too few hours in the day to keep playing it. Stays fun, no matter how many hours you pump into it.
Planescape: Torment - I've decided to catch up on older games that I never got around to playing years ago, so I picked up this one to satisfy my craving for an RPG. It's a... unique RPG, to say the least. And I mean that in a good way. It's weird, strange, has an impressively good story, but it's also showing its age a bit. Still, I'm enjoying it and if you like unconventional RPGs, it might be worth checking out on GOG.com.
