First let me say I have been enjoying this game quite a bit and appreciate the devs quickly releasing updates. 

Here is an idea to allow for MP balancing whether it is due to race inbalances or player abilities.  Simply allow for the selection of a resource multipler individually for each player/race to be set at the game start.  That way if everyone agrees that a particular race is stronger/weaker they can adjust the multiplier in the MP game setup to account for it.  It would also allow for players of unequal skill to still play together. 

From my (casual gamer) point of view I think the 1.03 changes made the game much more enjoyable (at least it did for me).  Please keep up the good work!
