Use you skills to make you own games with unique content. Dont make it "another private server over90000 exp *balablablaa*" 70% of community dont know any lang harder than "lua" and can only install server... 20% - mans who have a skillz but... game disign = NILL (yep you can only make "private servers" or steal ideas for make money.), and make money on first 70% and only 10% - who love this game and make it only for fun, and some ppl's who total rebuild MuOnline, and make really full custom game "MuOnline based"(respect!) with unique map (yea, no lorencia, no noria - full custom!)
Well, my imho - with that expirience, you can create you own game similar MuOnline! It would be great!
