The morons at Interplay did this with Starfleet Command and they’ve decided to do it again with Starfleet Command II — the game ships with a bonus disk, but the only way to get the bonus disk is to pre-order through the Interplay site. What, the money I spent at Best Buy just isn’t good enough for them?
Normally I completely detest software piracy — people are always offering to burn game CDs for me or ask me to burn some for them, and I always politely decline. I make an exception for this sort of “not available anywhere else” nonsense.
