This game is great, but sooner or later, it's going to have to evolve, or no-one's going to be playing it anymore.MOO made an attempt to evolve, but that didn't work out right. Not all sequels are accepted by the game's following.
True, but then again, Stardock isn't like Microprose.

Every installment and expansion of the Galactic Civilizations series has, overall, been a drastic improvement each time. I think they have a proven track record of evolving correctly.
This is my favorite game right now, but five years later, I don't think I would be happy with just Twilight of the Arnor.
You could get the download version of the game, archive it and burn the archived copy and Impulse/Stardock Central to the disk as well for future storage.
If you do that, can you re-install the entire game, plus all the expansions and updates solely from the burned discs? Is it like having the official CDs in your hands?
