better yet allow people who reboot their comps to rejoin.
Impractical. You would have to save all of the game data on other people's computers and resend that info to the player who will rejoin. Do you know how large an FA savegame is? It's several hundred MB. A system that allows a player to reboot his/her comp and rejoin a game would be unfeasible.
But the other suggestions are fine.
I didnt realise the save games were that big.
Anyway, we should be looking to the future and bradband speeds are getting faster and faster, and the game is likely to be Peer-to-Peer as per Supcom/FA Supcom2, so torrent technology might help with such a download.
It might not be as big of a deal as you think.
If the game is going to resemble FA in any way in that you could if you wanted have a game that lasts an hour or more, then I sure would welcome such a feature.
Regarding Supcom 2:
and wtf, now i have to upgrade everything BUT mexes? great ...
