I have had a lot experiences with DLC this gen, but I assume you're talking about the game adding kind & not the just measly add a skin kind that doesn't add value, but only made things prettier? The latter I can understand but didn't care especially when there were different kinds depending on where you pre-ordered it or depending on the platform. That sucked. Talking about you Batman: Arkham Asylum & Arkham City. Absolutely loved all the Red Dead Redemption DLC. In fact, I think I have it all except maybe one pack. Best value for my money? RDR Undead Nightmare. Absolutely loved that. I wouldn't have cared if was on-disk day 1 & sold as separate DLC either, but in general don't think I'm much of a fan of that. Upset? Not really, can understand it.
DLC that didn't really get off the ground? Kinect Fun Labs & Game Room. Game Room had so much potential. In the end I only really liked one game enough to buy it. I think Rock Band, Guitar Hero & Dance Central were good DLC that wore out its welcome too fast. I'm sure they made lots of money off that content. Wished buying the game DLC would have been tied to Zune music & video content. Missed oppurtunity there.
As for non gaming kind of DLC, I'll be upfront & say yeah I bought my share of it, but most of it was the free kind. Didn't spend a lot of money on avatar items, dashboard themes or game pics, but I did buy some.
One thing I was upset about: not being able to make & sell our own wares on the Marketplace like J Allard promised with Velocity Girl at launch.
We did get the ability to make our own 360 games with XNA/Indie Games & that was freaking cool(for those that could do it). Hopefully the new Durango Marketplace is much better for Indies & entrepreneurs alike.
