I had a chance to spend some time with both a few weeks ago. I am a fan of both Iron Maiden (the band) and Deadpool in general. I had high hopes for IMDN based on the opinions here.
I played both in barcades...which I am sure makes a bit of a difference.
I did not really enjoy IMDN much. I found the shots unsatisfying repeatedly. Now, I won't pretend I got very far into the game, but my initial impressions just weren't that good and I spent around an hour playing it. Maybe the shots are harder? but for starters that upper flipper in the middle of the pf just annoyed me. It didn't really 'do' anything, just a dead end. I thought the center PF was too open as well.
Deadpool on the other hand I liked a bit more. I'm not sure I liked it enough to buy one NIB though. It was hard to hear any of the callouts so I was just kind of going with the flow.
I expected to really like both, now I've ended up going in another direction. I guess it just goes to show, play a game before you commit to plopping money down on it.
