Rockstar DLC is generally pretty good. The lost and damned, ballad of gay tony, the 2 DLC's for GTA4 come to mind. The undead nightmare DLC for RDR was pretty good aswell.
Actually im going to say Old World Blues for this one, as you can tell by the pic fallout is my favourite gaming series But I choose Old World because it actually has a lightness in tone and you learn ALOT about the characters specifically Elijah and Uylessius if you are paying attention plus you have a dialoge with your brain which is incrdible in its own right.
Horse armour pack for oblivion Trololol Lair of the shadow broker was a great dlc, had some awesome combat in unique settings, and also fleshed out the characters heaps
To be honest I would have to say it would be a tie Between Mothership Zeta and Broken Steel. Both for Fallout 3.
Never tried it to be honest. I do own the fan pack where it gives you all DLC's but I found time to check it out.
Shivering Isles for oblivion if for anything it added tons of hours and replay for an amazing and adictive game (even if it was "dumbed down" from morrowind) btw...SKYRIM SOON ;D
I agree with everyone saying The Shivering Isle for Oblivion. I spent a ton of time on that DLC just wondering around it's amazing environment and doing all of the (awesome) main quests for it and side quests and dungeons.
Oke, I have no Idea what everyone is talking about so I went to a friend to play The Shivering Isle for Oblivion. and because of that well, I got it also for myself and to be honest I'm addict, so maybe for Stalin or for someone else to do an LP of it would be a great one
Well, not sure if TF2 updates count as DLC, but damn theres a lot of updates and content being constantly added to the game.
