Useing sonic RoboBlast for RP?

I think this game would be great for RP for a couple of reason, but one flaw is that i don't know how to make maps and so on, and i'm nervous about the doom engine have a map level size.

I do think if some one made the map big enough and added enough stuff one could make into a MMORPG in a way. but you would defiantly have to download the mod separately because if it was through server download would probably take forever...

Another good thing about this game is that it doesn't require much computer power meaning lots of people no matter how cruddy there computer can play.

So what do you think? and if you know does Doom engine have a map size limitation? and if it does is there a way to get rid of it?

I know this is late, but, SRB2 is a personal favourite place of mine to RP in. A good wad pack is SF-94 City which can be used for awesome city RP stuff. It's very good, though the problem is there's not much character customization, I suppose? It's solid otherwise - with actual space to run around. There's also some lua files as well as a custom one I have which is called RPmod, that adds chat ranges (so you have to be within a certain distance of people for them to hear you IC) as well as different chat systems.

For example, you have whisper, say (normal), yell, god (absolutely enourmous range), OOC and events. These are all tied together to basically make a pretty good RP "universe" I guess. In general I think SRB2 has a lot of potential. It's just a matter of using imagination in a LOT of cases.

I've never heard of this thing. Where could I find it? The idea seems interesting enough.
