I can't imagine spending $50 for a racing or sports game with no online play anymore. SSX Tricky was one of my favorite games, but I won't be getting SSX3 because of no XBlive support. Deathrow sounded interesting, but no XBlive support. F-zero, Mario Kart, NFS Underground, Fifa, and even Soul Caliber II are AAA games, but I find that I am no longer interested because they are missing this feature. Sure, I like to have my occasional single player-only experience like KOTOR, Zelda, Mario, Metroid, Baldur's Gate, Buffy, Ninja Gaiden, etc. But for games that live and die by multiplayer, my expectations are way too high now.
