I'm all for patches and all, both SP and MP, but arguing SP is the priority is a bit shortsighted:
- Most players won't finish SP at all (I think Skyrim average is like 25%)
- For the few players that do finish SP, most won't make a second run
- Most of the lifetime players of SP have already bought the game and those that wanted to finish it already done so
- As for the bugs themselves, there's nothing game breaking that I'm aware of. After completing everything except for 3 areas, I haven't bumped onto a SP bug except for 1 very minor quest in the Western Approach
On the other hand:
- MP doesn't end 50 to 100 hours after your first run
- MP will bring extra $$$ with Platinum no matter how ridiculous the odds are with RNG
- MP has game breaking bugs that plagues a relatively large amount of its user base
- They're bleeding MP players with their inactivity over bugs and glitches
I'm not saying SP patches aren't important, because they are, but MP is in a freakishly bad shape right now. It's like at the hospital emergency, do you provide medical attention to the guy who has a sprained ankle first or the guy's that's bleeding his life on the floor at an alarming rate? I rest my case...
Woah, that bolded comparison is not good. The point of TES is everything but the main plot, BioWare games are an entirely different genre that is far more plot- and character-driven, despite the superficial similarities to Skyrim of Inquisition's exploration and sandbox features.
Now that we're past that, I think it's hard to really debate this based on the points you bring up because I'm not aware of actual data. It is also kind of complex because there is an endogeneity problem with the variables laid out here (people may be unlikely to go for multiple playthroughs, but a good patch may make a certain number of people who wouldn't otherwise, play through again). A lot of the other points are speculation or based on the experience of other games which may or may not have informative applicability to this one.
Also, there are definitely a lot of major bugs in SP that need to be fixed, there are so many threads on these in the SP forums that it is perplexing to me that you're simply asserting they don't exist. Furthermore, different people consider different things injurious to their experience, e.g. while the rigging/clipping issue with the elf model that has like an 80 page thread dedicated to it is not "game-breaking" per se, it's a serious degradation of the SP experience for a lot of people, many of whom have held up or not started an elf playthrough for this reason.
As for MP, I could say that for a lot of people, the marginal utility of DAMP will in fact end after 50 to 100 hours. Whether that's due to the low amount of content, lack of variety, frequent bugs, connectivity problems or whatever, this is a personal calculation. Some people will play 1000+ hours of SP and that's valid, too.
The point about Platinum is good. An analogous situation exists on the SP side though, because the quality of that experience affects how likely people are to purchase SP DLC and future BW titles.
The bugs thing is subjective. Only BW has the data that allows them to make that kind of judgment. The bugginess of MP affects me a lot personally (probably more so than the average player, because my normal gaming group from ME3MP fell apart due to how forbidding the entire DAMP experience is to players with less than stellar connectivity to each other), but I'm not going to make a strong statement that MP is in a worse state than SP for the player population at large given the amount of players who could be helped with the available resources because I don't have that information, and neither does anyone else here.
