Head starts count for a lot in the games industry; Sony had that. Sony had a better plan going in, a plan that MS is starting to successfully emulate while developing their own unique approach. There's no denying MS got off to a rough start. But things are starting to turn around, and Halo is a big part of that. FWIW part of the Halo culture is replay. The campaigns are incredibly solid and have huge amounts of nostalgia attached to them; even though the 4 Halo games have been out a while, 343 is attaching new content to the MCC. The big difference between 343 and Bungie at this point is that 343 has built a reputation for listening to their customers. At Bungie, it is an inside joke that customers get so furious about DeeJ's style of communicating. I can appreciate that Bungie has a vision and they are sticking to it but at some point something has to give. Bungie is losing sales under their current plan and ultimately that will affect Destiny, a game I love despite its flaws.
