I think the console looks awesome but the controllers don't even deserve bare minimum credit since the color scheme appears to the only custom change made. I can't believe how great the console looks and then they did almost nothing for the controllers.
Seriously, they could've had the character on one side and the X-Men logo on the other. They could've used effects lightning for Storm, fireworks for Jubilee, claw marks with "Snikt!" for Wolverine, etc. or character specific scene shots like the console has from the series. There are plenty of ways they could've done more.
Basically the only cool thing about the controllers is the box so they are essentially selling these not to be used and instead sold at some far off Comic con. Sad because I would've bought one in a heartbeat to use if they'd gone a bit further. Oh well.
