Ah, Spore - I had countless hours of fun with that game, and reading this almost makes me want to reinstall it. I believe the last time I played, I built my galactic empire to a point of total stagnation; I had about 100,000,000 Spore-bucks with me at all times, too many allies to count, and just as many foes. Most of my income came from purple spice, which can sell anywhere from 20,000 SB to 80,000 (and maybe even 90,000) SB a piece - of course, it also depends on whom you're selling to. Since purple spice is a fairly rare commodity, most civilisations buy it for a decent price; but others that have a nearby star or planet with the spice might not be so fain to the purchase; it's all about "supply and demand", and even though the economy and trade in this game is extremely bare-boned, it's satisfying enough to keep a person playing well past their bed-time (if they have one). My galactic conquest ended when I chose to drop a planet-buster on the home planet of this empire that had been pilfering my spice slowly over time, demanding payments to keep a temporal peace, and overall being an arse to my allies - after that, everyone hated me, lmfao - but by that time, I didn't really care; the game was pretty much over. ANYWHO! I highly recommend this game to anyone who's not played it - it's well worth your time. :3
