As usual, I'm late on the good stuff. I haven't played any of these nominated titles.
I would like to get in on them, don't know if I can before the voting closes.
My first thought is Castle Crashers but like I said I haven't been through any of these titles. I've been waiting for the prices to come down and have had problems with content I bought not being available if I were playing without an internet connection.

I'll post to the Arcade Meetup thread to bump it up and see if anyone else wants to try these out and join the Co Op Arcade gamertag so we can find you.

From what I've played, Castle Crashers is a full step above everything else, though I also have a huge soft spot for N+ and would love to give it some more recognition.
