this is from a long ways back, but DLC implementation
And DLC support.
The DLC-out-the-gate then holding back / not making anymore DLC until you have a tie in with another Halo game bullshit needs to stop.
Then making it so your later disc release only plays maps from one map pack and doesn't even support loading the other DLC is icing on the shit cake. It's not like they're new to outsourcing, just let Certain Affinity make a ton of maps and release them regularly. Use them for more than remaking Hang Em High over and over again.
Having it happen TWICE now with Halo 3 and Reach pretty much guarantees that I'm not going to buy 4's DLC until it goes on sale.
