I don't really enjoy online multiplayer, with a few exceptions like Splatoon or Mario Kart 8, so its always frustrating when you play a game where the single-player campaign feels like an extended tutorial for the online multiplayer mode.
If the multiplayer modes don't noticeably hurt the single-player campaign, I have no problem with it. But if they're giving me a 6-hour single player game for $60, I have a big issue with that.
The biggest problem will be revisiting these games ten years from now. They're going to feel like incomplete games once the multiplayer servers for them go offline.
