I'm sort of with you.
But i do consider some DLC worth it. I mean the idea behind it is to make more game for those that want more game is in itself a great idea. What isnt is the way this gets abused by publishers that instead of doing that, cut slices from the games to later sell as DLC.
I would say i like the elder scrolls/Fallout DLC. From what i hear the GTA4 DLC was good aswell. Despite beeing ripped off with day one DLC on Mass effect 3, the DLC for Mass effect has been enjoyable aswell.
Despite all the overeactions i think Street Fighter 4 did quite well with later versions of the game with more goodies. It was stuff developed after the game released.
So, NO to DLC, unless its done right and the way it was originally envisioned.
