$45 is what they want for buy it now. However, its not what they'll get for an 8 year old game that most people don't even know exists. If you don't want to bid, Amazon has it used for $5.97.
Very interesting, so is that all I need to buy or do I also need SFC2?
Orion Pirates is a "stand-alone expansion" of SFC2. OP has everything that SFC2 has, and you don't need SFC2 at all. The only thing that SFC2 has that OP doesn't is the specialized single player campaign for the empire races, but you can download that for OP anyways.
OK you guys talked me into it, I just ordered it from Amazon, 10 bucks inc shipping. I guess I wasted 8 bucks on SFC1, maybe I can sell it on ebay or craigslist. So where do I download the campaign that is missing?
I will look for a link for those campaign scripts.
I don't recommend selling SFC1! The single player campaign for SFC1 has you join a special organization for each empire (like the Federation Special Task Force for the feds, the Tal Shiar for the Roms, etc.), and this gave you a whole bunch of unique missions. They really were a lot of fun.
SFC2/OP's campaign is more cookie-cutter, with a lot more generic missions-- you can't join a special ops force, and you don't really get any race-unique missions. Like Tus said, the SFC1 missions were never ported to SFC2 or OP, like the SFC2 were ported to OP.
