sckeener said:Since you only know D&D let me mention the OP:
the OP mentioning building a munchkin gurps supers character means that the choices are wide open. You do not have to be yourself...but you can if you want...you can have your memories...or not...
any setting, race, class, feat, power...whatever....after all for all I know the super hero character the OP created could be an ultra powerful drow with 20 levels of wizard (converted to GURPS) as himself.
I see. In that case, creating a custom homebrew setting for myself for this purpose would be the most sensible approach, which I would indeed take.

Still, I think this thread is supposed to be about published gaming worlds (hence no homebrews), of which I know only the various D&D settings. Out of those, it would partially depend on the interpretation of the rules. For example, if Planescape allowed access to all the other worlds, as was its original intention, but as is no longer really the case, I would go for Planescape and make myself somebody ridiculously powerful and able to travel to all the worlds of my choosing. After all, why restrict oneself if one can have it all?

Out of such settings, I have a specific affinity for Dark Sun, but it is a bleak and inhospitable world. I guess it might not be all that bad, however, if one is somebody powerful, such as a mighty psion/preserver. Nevertheless, it has powerful beings that dislike competition and would seek to hunt one down, so unless one makes oneself truly ridiculously powerful (which is nice and dandy, but than again, what world would be bad if one had ridiculous amounts of supernatural power at one's disposal, so it kind of defeats the purpose), it would probably be more prudent to chose yet another setting, perhaps the Forgotten Realms and be a high level wizard there.
Whatever the setting I would chose, however, I would definitely chose to be somebody with supernatural powers (wizard/sorceror, psion/erudite, etcetera), chiefly due to their conspicuous absence on our very own Earth and therefore the new possibilities they would offer me.
