I'm planning on buying the game, and to avoid the S+H cost I am looking into the download version. As far as I can tell, you download it through Impulse, which seems analogous to Valve's Steam. I am familiar with Steam, how I can download and install my games on whatever computers, no limits, and for the most part the only way to lose my games is to compromise my password. How does Impulse compare to Steam, and are there any concerns about how it works/limitations? I've heard good things about Stardock (which is how I found this game), so I expect there to be no issues, but I want to verify from users how it works out.
Also, as far as LAN games, does everyone need their own copy, or is it possible to run multiple games from one copy (like I do with Starcraft/Age of Kings/Civilization 3)? Do I need a physical copy to do this? This doesn't make or break the game, but I may as well be aware of how this would work.
Thanks for any input (sorry if this is off-topic); hopefully my next post will be asking how to stop losing to you guys in multiplayer matches (better yet, why I somehow keep winning).
