I have to disagree.
It's so much more than just a good game. It lets you go creative.
Sure it has it's shortcomings (random loot and overall balance) but it delivers on the most important aspects every game should concentrate on - it's fun, it's not boring, not irritating and not annoying.
I'll just continue to praise this year. So far the only RPG title I wasn't satisfied with is Bound by Flame, I've expected more after Mars. Honestly, so much fun with fresh RPGs, not just Original Sin, but also TsoT, R3 and TitS I haven't felt in years. And for sure it's not the end of awsomeness, new KB is just about to be out, then we get W2, AoD, DA3, probably even more.
RPG of the year will be a tough call but if you ask me, although not a completely perfect game, D:OS deserves it. So far, dunno if those newcomers will nail everything perfectly.
As you may notice I didn't mention the mainstream grinder that's listed as RPG here and there, praised by critics and audience, I mean advertised by critics and audience. Not gonna buy that one ever and am not ruining my braincells with such things, sorry.
