I only recently bought this game (second-hand). Still haven't tried it. Good to know I'm not missing out on anything
I never bother with downloadable content of any kind.
I hate the idea of a game dependent on both disc and the online 'Drip-Feed'; an online drip-feed that is slave to the mothership pulling support at some point in future. Plus subject to a new release of the game with all the DLC integrated in future (ha!), screwing over the most loyal, highest-paying early-adopters. My motto: If it's not on the disc, it's not part of the game.
In this case, I am missing out on nothing, which is rare these days
The disc itself seems like a 'challenged' lifeform these days; expensive to manufacture, distribute, etc. Which only makes me treasure it more.
