Hmm, rpgcode is somehow real... Altrough you won't be able to make a game that will only consist 1 program without the main file etc... And it's somehow dependant on all your boards, items, characters etc (altrough I don't use personally any of default items, I make all my own programs)...
Multiplayer game done with tk? I'll get to check that out, cool. Trading? You mean trading WHAT? Items? Code parts? Hmm... This should allow me to make a diablo-esque game considering that in my game you can, ehm, wll be able to (when it comes out, ehm, if it comes out Wink) have random-generated items and upgrade them, forge them, enhance them, enchant them, so trading them would be cool... Hehehehe.
Too bad I NEVER use any plugins because of my unregistered tk version... And I made cool BSs and now work on area-based one (where you move around and attack in melee or at range) without using any of them...
