The campaign was fun. I had never played COD the original before, so that was nice.
But I cant get multi-player to work. E-mail support with Aspyr was OK, but not great, and he just led me through all the stuff I already knew (repair permissions, make sure the entire folder is unlocked, open a port on the firewall, etc. etc.) after about a week of back-and-forth e-mails (never an offer to talk on the phone, so very slow in trying new things) I gave up. I would therefore say its overpriced. $10 for an older graphics campaign game, yes. $10 more for multi-player, but if no multiplayer, then you owe me $10 Aspyr!
edit: running 2009 MBP with 2.16Ghz C2D, 8GB RAM, Snow Leopard, over Fios connection. No reason this shouldnt work.
