The game is really fun over all, but there are a few issues that keep me from fully enjoing it (probably the same as others have posted).  The game freezes a lot on me while going from menu to menu, but waiting a min or so usually fixes it.  When joining pantheon games, I think I have about a 75% success rate (sometimes it goes to the standing screen and does nothing).  When the game is almost into joining, I get player left a few times (sometimes) and end up with all computer bots.  There is also the Cannot connect to a NAT facilitator bug that pops up every now and then (almost always on Custom games though).  I did get hit with the negative favor bug, but eventually got myself out of the hole.

The games themselves are very fun and I really enjoy the variety in pantheon.  I do not mind having computer opponents, though usually it is 2 people and 3 comps on each side for the 5 player maps.  Overall, I think once some of these issues are fixed, it will be a very enjoyable game, where now it is just mostly enjoyable.
