Prisoners on Isehara Terraforming Outpost should cost about 1500 credits. (it costs ~1300 on Akita) The reason for that is that GMG use Prisoners on Planet Miura as labour force.
Synth Paste cost could be reduced a little on Fujisawa Mining Facility. Miners cant eat that much. (on the other hand it sells for a common price in ropponogi which is much closer)
Gaian Wildlife costs a lot in Okinawa and various planetform operations. While it makes some sense perhaps it would make more selling fancy pets to rich folk on capital planets. Definately not a bug, just worth considering.
H Fuel prices from Okinawa to Newcastle can bring up to 167 c/second. Fuel prices should be reduced in Bretonia overall.
Too many profitable routes end up in Gallia, number of them could be reduced to prevent repetetive trading.
Synth Paste prices bring fortune in Kusari and prison facilities only. A route to Bretonia from Stuttgart could be made. And as Vero put it:
[17:59:13] Vero says: What frustrates me most about the Synth Paste is that you cant even haul it to 95% of the bases because the price is the same as at Stuttgart
[17:59:54] Vero says: hard to RP a paste run to manhattan knowing I'll loose money doing so
[2009.03.09 21:00:15] Wrathkin says: Yeah, so we'll still have to haul lux food to make profit any other way. I like to try to get at least every other leg make sense, but I've not found that yet.
Wine from Bufallo to Sain Paul in Minnesota. Very short and pays 150 c/sec. I definately think its a bug.
Plutonium from Okinawa sort of lacks routes. It can be sold in Omicrons and Gallia which is not very good RP. It can also be sold in Bretonia, but GMG ships cannot enter there. It can also sold for humble amount in RHeinland, but then again GMG does not pass there either. Perhaps a route to Liberty would be in order.
Ogashawa pays too much for H Fuel.
Thats all I can think of at any rate. Will keep searching.
