I have had sandbox style games, RP heavy games, games that come down to being little more then dice rolling killing monster...
All in all the rules never made one lick of diffrence. If I want to tommorro run a Hard Core Monster hunt with pregens named A...B...C...and D. I can run it in WoD. If I want to design a living breathing world and put my PCs init to see what happens I can do that in
4e.
I don't understand what people want
4e to say. "Here are rules for trade agreements between countries"
or maybe "This is how you design an economy"
IF I want to do that I don't need...heck after reading
3e and 3.5 DMGs I don't WANT...
WotC help in doing it. I can.
