The majority of Bethesda DLC is shit that should have been included in the base game.
And was, if you had the patience. I bought the FO3 expansions, because I was given the base game for free, but the others I've only bought as the combined versions, and don't even know what it's like to start a character without all official expansions installed and enabled, from Morrowind up through Skyrim (I never knew Morrowind without vampires or werewolves, FI). Until the expansions and CK have been out for a bit, and a GOTY or equivalent release is available, it's not
really released, just teasing the impatient and the console gamers.
Thing about Bethesda is that you can count on the fact that they will release a combined version, that it won't cost a bundle, and that the game will be vastly enhanced by modders by about the time that comes about (overhaul mods go from ideas to finished DLs pretty quickly, after the GOTY+CK are available). They and the community have a nice repeatable pattern set, by now, that many game publishers do not.
I'm still waiting for a suitable pack and/or sale-on-everything for BL2 (the holiday one was not deep enough for all that DLC, IMO). I loved BL1, but it only had a few that made anything, and they weren't bad...but that DLC list for BL2 is a cluster.
Metro LL has some silly ones, too, but the content ones weren't expensive, all totaled, were pretty good,
and were extras, rather than what should have been in the game--you wouldn't miss anything at all, not getting them. If all publishers made them like Metro LL's, it wouldn't be bad at all, IMO...but, at the same time, that won't rake in the monies like having content that aught to have been in the game would.
For the most part, though, games heavy on nickel-and-dime DLC and IAP I tend to not want to play
anyway, even not counting that part of them. They will tend to be overly-scripted, full of QTEs, renown for being buggy, require added DRM from publishers I don't trust (like Ubi and EA), etc..
