I doubt it. Not anymore anyway. Merc's an incredibly dated codebase that isn't really used anymore. Other codebases derived from it are, just not it directly. The same goes for DIKU. I wish the same was true of CircleMUD, but...alas. Not that CircleMUD is bad. I also wouldn't suggest that all muds running it switch to tbaMUD because I understand how difficult transferring work from one codebase to another is. I would on the other hand suggest people starting new muds based on CircleMUD try out tbaMUD before starting their project. I've honestly never known anyone to try CircleMUD and tbaMUD and not find the latter to be the more solid codebase of the pair. I also don't claim to know of everyone who has ever downloaded tbaMUD and looked at it so I assuredly won't claim no one ever has, just that no one I know of first hand has.
