[quote name='SqueeMK2']I wanna pick up Halo 1, but I'll wait'll it drops to $10 or so.
I've got it on PC, and mostly just wanna get the Xbox version for co-op. $20 just for co-op hurts.[/QUOTE]
I seriously doubt you'll be seeing Halo (for the Xbox) any less than $20, and certainly not $10, anytime soon.
It's still selling decently at $30, and the demand is still there. ... I mean you can't even find the game as a preplayed Blockbuster game @ $20, let alone brand spankin' new. Besides, many gamers still consider the original superior in some ways to the sequel (I don't), so the demand isn't fading like other games you can name.
Anyway, this is simply a weeklong sale; the game's price hasn't taken a universal price drop.
Bottom line: Snooze, you lose.
