Can't find these games on Amazon.com/half.com but found one copy on ebay, except that the price is a bit too high for me - $53 + $13.17 S & H, although I bought Backbacker earlier this year from an ebay company - Half.com for $45 + S & H. I'd do it again (spring for this game right now, but I'm waiting until mid-Dec if the game is still there), but currently I've spent over 40 bucks on computer games this month (bought from Ang at AP and on Amazon.com) and I don't want to overspend before the middle of the month at that $53 price. But if I can get it cheaper that would be nice.
Also I cannot find Central High at amazon/ebay/half.com, so if anyone has it that they're willing to sell, please post
EDIT - since my spending debt was already paid up several days ago, I decided to spring for that Synnergist on ebay. That and Central High were the only games I were after in addition to the ones already bought so far, (but found others).
