Either Warhammer Online or Red Alert 3, since those are the only two games I've purchased this year. Red Alert 3 was just hard as hell to play. The reflexes required to succeed are not something I have. It's a very well made game, and probably among the more competitive RTS out there, but seeing how it's obviously intended for experts, I was obviously disappointed when I discovered I couldn't play it worth a damn. Warhammer Online was disappointing not because it was bad, but because it was only average. It was a really buggy version of stuff I was already playing, so why switch over? Unfortunately I didn't realize this until I had paid like 80$ for the collector's version.
