Demigod was probably the most resent one. I make a habit of... *ahem* testing a game before I buy it, but I decided to drop the cash on it with nothing more to go on than a single recommendation from a friend, and the rampant piracy rates that hit that game. Morrowind I guess would count, or maybe the PS2 Neopets. The thing is, I almost never play a game I've never heard of before playing it. I had a friend who was raving about Morrowind's graphics, and I saw a convincing E3 trailer for Neopets. That was all I had to go on with those two games, but now Morrowind is my favorite game ever, and Neopets held me through a full playthrough for what should have been a fluff title that I pop in once and never look at again. It still remains as one of my favorite titles that shouldn't have been fun at all, let alone a really good game.
