A lot of things did, not just what you mentioned. It's a lot harder to replicate a high amount of data to a high amount of players in p2p, since you have to send that data to everyone you're playing with, and you're basically limiting yourself to residential connections/wifi which are still crappy and have a high amount of lag. For the kind of fast-paced games people make/expect nowadays, this isn't really acceptable anymore.
