Divinity: Original Sin was released during the Steam summer sale and has been hugging its #1 most sold list since (despite only being 25% off for a day and then full price since).
My opinion: This is the best RPG ever released for PC. It's a more colourful, more humorous Baldur's Gate. It's filled with high fantasy elements, although your only real friends are all humans. The pen-and-paper parts of combat and character development are extremely well-done (no dice for damage though!). The story and quests are incredibly well-written within the context of the game. It definitely does not hold your hand! No "go to X, collect boring_item_321". And it manages to add something to the whole formula, terrain transformation. Spill some poison on the ground, blow it up with a fireball to create a large burning area. Pull out your rain spell to create a fine mist from the burning area, now you got something to block the view - turn that into a lightning storm with some thunderstrikes.
The only bad part about the game is crafting. There's no interface for it, you just drag stuff on top of other stuff. You find recipes in-game but they are pure text descriptions that aren't always clear ("add some fire" may mean put it in a furnace and so on). And there are often a lot of steps needed, which makes it even harder since there are so many unknowns (add an iron bar - where do I get that? another recipe...).
Also, 2-player coop multiplayer and something I'm personally more interested in - they released the tools used to make the campaign. Mods. Mods! MODS!!! (game just released though, probably none out yet)
Anyone else playing?
