The problem with most perpetual multiplayer games is that they are potentially limitless time sinks. They are often inherently addictive with no natural end or resolution to them. Of course there are single player games that do this too, so it's not the only differentiator.

In contrast, single player campaigns (or co-op campaigns for that matter) are often story driven. They have a beginning and an end. They offer catharsis. If it's good, you may play through it again, but it will end eventually.

Yeah, different taste. You can see a few here argue that $60 for a single player game is not worth the value. Some want that sink to come back to and sink a few hours into. Some are pretty free upfront, so their monetary investment can even be $0, amortized by whales.
