Because the high oil price jets lose value. As a result turrets lose value. Also people have less gold to spend after the expensive oil. Lower indy prices make sense.
funny, I had the same thing happen to me, the last day suicide retal for 1550 for a 250 hit. Next reset I will just play to screw up someones set, since I've seen a lot of people do it it must be fun.
I am a theo techer in tourney and I can't keep up with the size of the other countries. Grabbing is tough since there are only ~20 available targets (unless I declare war I guess). I don't want to sacrefice too many turns exploring either right? Should I just accept that I am smaller then the rest or am I supposed to have explore batches on some days?
