MOO code is strange, its true. I have spent the last 15 years on MUSHcode. I've been on this game for several months now and I'm working with the Codewiz to try to add more MUSHcommands that make it easier for MUSHers, its already come a long way to make MUSHers feel more comfortable. I'd love to have more MUSHers come and suggest some more ideas to improve that... MOOcode is weird, but it does have some kinda awesome features too that MUSHcode doesn't have.
