I'm sorry did somebody say that bf4's only problem was heavy traffic?
Sometimes there's just no words lol.
In case you are referring to me, here's what I said "All those games are online games and the beeing completly unplayable had only to do with internet traffic. All those games did indeed have bugs, but they all also had non stop patches since day one." Try not to be a smart arse about it.
So I did say they had problems, and to some BF4, it was unplayable, not all, and maybe not to the same extent, some say the same about DA Inq, that it's unplayble. I'm not one of those. BF4 which runs on the same engine as DA Inq had several problems, seeing it was mostly new, and it was acting up on just about every platform. DA Inq is mostly PC problems.
The issues in SimCity and Diablo may have been due to online features and the like, but that hardly detracts from how bad the launches were. The issues with BF4 were more that the game was just flat-out broken to launch, and had nothing to do with the online traffic. EA probably could've made DAI online-only for the sake of DRM, but they didn't.
To address your other point, mods do not excuse the state Skyrim was in at launch in the slightest. While it could be viewed to add value to the game as a complete package, as far as game launches and general developer-side polish go it has absolutely no bearing whatsoever.
I really don't want to come out sounding like I'm defending the issues in Inquisition, of which there are quite a few. They are fairly minor, though, and for the most part shouldn't detract from playing the game for the vast majority of players. Given the scope of the game, that's not a bad launch. It would be good if BioWare got in the habit of smaller hotfix patches, though I don't know if any of the patch delivery platforms they have available work particularly well with that approach.
Again, you're trying to compare multiplayer only games on their launches to a game that barely has strain on the mp front, it's completly different. Also DA Inq does have DRM, the denuvo DRM that many say slows down and glitches up the performance, not to mention the amount of people already filling law suits against this DRM that supposedly is destroying SSDs. DA Inq isn't online only but it does have DRM, that Denuvo one that has today been hacked for the first time, and Origin's DRM.
About the mods, they don't excuse the sate of Skyrim at launch, and it still got great reviews and loads of people who loved the game right? so does DA Inq, if you can't see where I'm going... The two major differences in this case is that DA Inq doesn't support mods and it's also taking a lot longer to patch than most other triple A games, and yes I'm talking about multi platform games too.
