If the argument is that SM2 is successful because it limited it’s scope to execute a smaller number of features well, I don’t think that holds up. It took on three different types of games and (imho) executed merely okay. What more could they have added? Open world? MMO?
I think the more plausible explanation for the sales is that it’s Warhammer, it’s pretty, and SM1 was good.
Who praised them? But I don’t know what measure we’d use to determine the general reception of this particular feature. Particularly given that almost all video game journalism is mere marketing. So that’s probably not a fruitful point to argue over.
Instead I’ll offer the things that I think earn the competitive multiplayer a poor rating.
