^Well, I had a PS2, so there really wasn't much to download last-gen for me. I feel kinda old too seeing all the recent games listed though.
Now that I think about it, you're right, PS2 didn't have much for online at the time yet, even Xbox didn't really have a lot of DLC options. Crazy how much has changed in such a relatively short time.
Not technically "DLC," but I consider it a precursor. My first ever experience with "DLC" was expansions for various PC games.
My first ever experience with "DLC" on a console was with "Grand Theft Auto: London, 1969" on PS1.
First DLC I bought on PS3 was some stuff for "MotorStorm."
