I'm finally having to post this up [s]sans-playtesting[/s] because so many people keep joining my game and then quitting online that I'm scared someone else is going to steal the credit.
[s]I have playtested this with 2 people, and it worked just fine. However, when I tried with 4, people started saying wtf! this is crap! in the first 5 seconds and then it oos'ed, and I don't know what happened.[/s] I fixed the problem here. It doesn't happen anymore.
The game includes a cinematic and a tutorial, which you can selected to watch or skip at the beginning.
I still have a few balance changes to make, but like I said, I don't want anyone else stealing my credit for this.
Controlling the river crossing points gives you a slow favor trickle. When you reach 200 (which is the reason you need to be Zeus), one of 4 gods (depending on which team you're on) will help you out. These are potentially game-changing and my favorite part of the game.
Update: The game now works with 4 players. Still a couple of bugs, but the game is still playable start to finish.
