One particular game and personal favourite of mine, which I also listed in my most loved games of 2013, was Beatbuddy by Threaks.
They won Best Serious Game and beat the hugely acclaimed Crysis 3 for Best Game Design. Both awards are extremely well deserved and impressive. Congraulations to Threaks and everyone else at the German Developer Awards, which seems to display a real love of gaming, by fusing AAA and Indie games as being worthy of similiar achievements.
Beatbuddy is currently 75% on Steam as part of its Christmas sale, so there's no excuse for not hopping over there and grabbing this game. It's really worth having in your collection and the price right now is excellent.
