I played 1 hour of Haunting Grounds and never touched it again, but it's not because it's bad... It's because I'm a scaredy cat, haha. I watched my brother play through the entire game and helped him solve the puzzles, but I couldn't get myself to take the controller. We did complete the game in the end though.
God of War: Chain of Olympus helped me take out my anger when I wasn't feeling too well, and I enjoyed it a lot in that time, but I've put it aside since then and I just don't feel like I'd really enjoy it if I wasn't mad, haha. I don't know, maybe I have a wrong feeling, but I don't feel compelled to finish it, at all.
The Lord of the Rings Tactics. I LOVE LOTR, and I usually like Tactic games too, but man this game is too hard. I can't have fun with it, I tried playing 3 times, each time I gave up after 20-30 minutes.
TMNT 2: The Arcade Game on the NES. I played that game for hours with my neighbour back in the days, but we never were able to beat it. I gave up all hope and don't really want to play anymore. Then I had a friend play it for his first time 2 years ago, and he beat it just like that in one sitting. Damn him!
Okay, they're not all recent, but it feels good to have talked about them anyway
