Well, I don't know of the other guys but, I have chat with Demonkai here and at mugenevolution. Seems like a cool cat and working hard to make another awesome character for mugen. Still, I would like to see what his final update to his terry will be. I feel like he has displayed plenty on guild and other forums of his progress of his creation. Vids, updates and productive progress.
V-nix is very talented fellas and I know the this from working with him. Heck, he cook something up for my BC2 screen-pack and wants I have finish installing everything you will see. Just take my word for it. The man knows his stuff and makes me look like a rookie all over again.
