I've looked through the files and find up to a few adjustments to the tempo. Ammunition. Speed. And building healing does not make much difference to the standard game. But I can not remember the server of n4b what was different there. Too long ago. Can someone give a summary of what the difference was.
Mad jumps (high), pretty much inf. stam and mana, workers built faster (i think so), shock was also really OP, but can't remember how it worked tho.
I think weapons range was longer as well, as well fireball didn't have the "aim" choice, just spamm it like a madman.
