Don't back peddle. You're right!
Consumer behaviour dictates how severe the DLC issue becomes.
Buying the DLC is definitely part of the problem. At least waiting for the one or two days when the Porsche Pack was on sale(because nearly every product gets a reduced price at some point) shows Turn10 and MS that consumers have brains and will power.
I wasn't able to take advantage of the Porsche Pack sale. And never bothered to look at it again since then. We're now a couple of months shy of Forza 5. Do I feel like I missed out on anything by not buying the Porsche Pack for Forza 4? Nope.
Don't feed the money-hungry publisher and developer trolls. No different than forum trolls. They'll just keep coming back for more.
but i dont think they are dicks.
