MUGEN - What do you think?

So i've been looking through a few posts, and mugen MK games seem to get a pretty bad rep - i can understand that games like MK Anthology and MK Chaotic have wildly inbalanced AI and cheap, badly sprited pallette swaps as characters, but there are some excellent MUGEN MK's out there. MK Outworld, and the cancelled MK Bloodstorm were great examples. What's your opinion on MUGEN and MK?

mugen is limited but if you put time an effort on it you can create great things with it. sadly a lot of mk mugen projects are just clones.
