the bs_fantasy from the old modules site? i thought it stopped working ages ago...
other then that there s only one other bs_fantasy module, and that s a core anope module.. which does exactly what you described. the bs_fantasy that ships with anope provides the !voice,!op, ... commands, no others. there s also a bs_fantasy_kick and bs_fantasy_kickban that come with anope, but they should all be loaded as core modules by default.
i dunno what you meant with "rest of commands", but my bs_fantasy_ext on the modules site has !help and some others....
your question isn't very clear though...
