I own both and have previously owned LOTR. IMDN is absolutely awesome, and fast/chaotic and fun to play. So is Houdini. I’d say IMDN is a little more predictible in terms of the shots, and while it is super fun, most games are pretty much the same. Houdini, on the Other hand, is different every time. But Damn is it hard. I doubt you’d regret trading in LOTR for either. Make sure you play a couple more games on Houdini so you understand the unique shots and how you really have to play with a lot of nuance to get the shots. You can’t just blast the ball everywhere like on most games. For certain shots you have to really be very gentle. Game is awesome
