That is awesome and it def took a lot of work to come up with something as brilliant as this. There was another guy that went by the name bender33 who made a mini DK. I wish I could do something like this, I would make all my favorite games as minis. Wouldn't have to worry about space then.
I've seen a few people make mini Mortal Kombat machines using those Jakk's plug n play systems, but I have to say this blows them away. It'd be real interesting to see what this thing would fetch on eBay given how the MK's did.
