One word: All!

Well that would be ideal. Personally i am a huge fan of choices. I want to go my own special little way. That usually means i have something in my head i want to realise and to do that i need as much material as i can get. Classes, Races, Sub-everything. A shade transformation ritual? Of course! Spells to go unsusual ways?
Yes please!
We are on a nautiloid that was somewhere in the Astral, right? Didn't that plane somehow connect universes? Ravenloft? Eberron? Dark sun? Krynn? Visiting all layers of the Hells and the Feywild? Oh boy smile
Well i could go on for a while but i fear a game that immense will not happen.

A few years back i was thinking of creating an MMO playing in the realms and had really nice (IMO) ideas. But i became an engineer then, so much for that dream :P
