Retail Requirements

it doesnt require impulse to play the single player game, but it does require it to update and do multiplayer.

Ok thanks. Most likely wont be getting it then. Already have steam and it works great, dont need another one on my system.

Don't have the hard drive space?

I've got steam and impulse and really they don't cause problems with each other. Impulse is very UNobtrusive, so don't avoid demigod just on that basis. You only use impulse for updates and installation.

If anything, Steam is the more obstrusive of the two.  In fact, unlike Steam you don't require Impulse running to do multiplayer.  And if I'm understanding how Impulse Reactor works, you don't even need it installed to do multiplayer (just to update)

Impulse is not required to run the game, only to get the updates. For all practical purposes you could uninstall Impulse between updates, and the game should continue to work fine.

nevermind, i found the answer on another thread.
