Personally, I think online play (with few notable exceptions) has become a crutch to prop up mediocre to bad games and encourages developers to cut corners. The most notable example I can think of is Halo. The first game was great. A little repetitive but what game wasn't circa 2001. Great game design, well thought out controls and a nice story synthesized from and inspired by a ton of classic sci fi literature. A shining example of the genre. Then along comes Halo 2. Still the same great gameplay but the game itself was short, too short. It was basically an expansion pack sold at full price that brought multi-player into the mix. They both were only worth The same goes for Halo 3 except the single player mode, while even shorter than 2, did not live up to the standard set for it by its predecessors. I don't mean to belittle the Halo sequels but most people identify with them. Now contrast that with Crysis Warhead which was basically half a game that introduced "real" multi-player to that franchise (the MP for Crysis was a half hearted effort) but retailed for a reasonable $29.99.
