TOTAN. I had only played one once in real life at Allentown, and then The Pinball Arcade came out and I played a ton of it on my iPad. I loved everything about it and had to have one. When I finally got the machine, something about it just didn't translate from TPA and I didn't want to touch it. The game is beautiful though.
LOTR. Love the theme, the music, and the DMD animations, but I hate the gameplay. Feels very slow and clunky to me. It was a huge hit with guests due to theme, but I didn't find it fun at all.
