I made this account just to add that I wouokd love to see Castle Crashers come to the PS4 aswell.
In fact, I used to play CC on a daily basis on the PS3, with many friends for years. I personally know of about 50 people who would buy this day one.
If they were to do something truly epic, such as putting Castle Crashers and Alien Hominid Remastered on a physical disc copy for the PS4, I think it would sell like crazy. Get in touch with Limited Run Games, FanGamer, or iam8bit. I'm sure the would live to publish the physical media version.
