Well, I think that SD learned /alot/ by publishing Demigod. I think that Elemental will show a massive improvement from the mistakes that GPG made that SD has learned from (eg, they are writing the netcode from the ground up themselves instead of plugging in a random library).
Demigod did 2 things really really well:
- Gameplay (it's so much fun to play).
Everything else... Elemental can benefit from and stuff.
Plus, we'll get a few good features through Elemental (like any improvements through Impulse Reactor).
