Is Dial-Up connection enough to play multiplayer games?

From personal experience - Dial-up connection is enough to play 2-players game and talk by Teamspeak simultaneously.


How much traffic is spent for 1 hour of playing?

It depend on game intensity. If you play 2-players game on a small map then you have about 4-5 Mb per hour. If you play 8-players game on a big map and with large armies - then traffic is much higher. Average value is near 10 Mb per hour.


The game says "This game version is different". What should I do?

1. Probably, mod versions are different or you try to play different mods. Always discuss mods you want to play and their versions before you start.
2. You don't have Patch 1.04 for Generals Zero Hour. Download and install it.
