“Let’s forget about what the actual promise of a game is and whether it’s suited to a narrative or competitive experience. Take that off the table for a minute and just think about the concept-free feature list: campaign, co-op, how many players? How many guns? How long is the campaign? When you boil it down to that, you take the ability to make good decisions out of the picture. And the reason they do it is because they notice that the biggest blockbusters offer a little bit for every kind of consumer. You have people that want co-op and competitive, and players who want to immerse themselves in deep fiction. But the concept has to speak to that automatically; it can’t be forced. That’s the problem.” - Gearbox’s Randy Pitchford
I absolutely hate it when a dev shoehorns a multiplayer mode into their game. If you want to focus on the single-player experience for the consumer, go right ahead. I’d rather take a great single-player game than one with less focus in single-player and a tacked-on multiplayer experience.
