I noticed in the recent game I played, which was a 3v3 on Blindside, that various things costed around 125 credits less than they ussually do. I can't remember anything specifically, just that there were some buildings that should have been 750 that only cost 625. I think metal/crystal extractors are normally 250 but in this game they were only 208. This was in the begining of the game and the only thing I had researed was Assailiants and Volcanic Occupation.

Is there an option which effects the cost of things? I was playing at normal speed and fast research speed, with random resources. I always play with these settings and this was the first time I noticed a difference. I'm guessing maybe it had something to do with the random resources? Or is it the map?  Did our team get some sort of bonus because we had a TEC player, a Vasari player, and an Advent player?
