Just a warning: I'm an Australian, and when I bought from GamersGate on my credit card, it was charged as "cash" (something to do with GamersGate being related to gambling) which added an extra $2.50 (AUD) and I paid $0.02 AUD interest on the "cash" sale. See my transaction history:
20 Jul 2009 PAYNOVA GAMERSGATEAB STOCKHOLM SE FRGN AMT: 4.99 U.. S. DOLLAR 6.43
20 Jul 2009 CASH ADVANCE FEE - CASH S UBS 2.50
26 Jul 2009 INTEREST CHARGES - CASH 0.02
I phoned my bank and they have reversed that extra charge and interest. But just saying: be careful with using GamersGate!
I love supporting quality indie titles: mount&blade, AI War are others. I also bought the penumbra pack earlier from steam and gave it to a friend of mine who played and enjoyed it.
Best of luck with getting your next title out there, I will definately be here to check it out when you do!
