saarconvoy: I got Thimbleweed Park, Metro 2033 Redux and The Guild 2
I know nothing about The Guild 2, but as far as I'm concerned, your piñata purchase was already worth it for Metro 2033 Redux and Thimbleweed Park alone. Well, if you're into those sorts of games, of course... I got Heroes of Might and Magic 3, which apparently is a great game, but I'm not even going to install it, since it's not my kind of game at all.
As a major adventure game geek, having grown up with all the LucasArts classics, I can't recommend Thimbleweed Park enough; it's downright one of the best -- if not THE best -- point & click adventures I've played in recent years, right up there with the first two Monkey Island games (also designed by Ron Gilbert) or Day of the Tentacle. If you don't care much about point & click adventures, though, I can see how this piñata means nothing for you.
