You're not the first one to dismiss MP games even if it is an option, and I absolutely don't get it - why should that change anything ? Maybe because it would imply a bit more testing and developpement ? DOS is proving that a game developped with Coop in mind from the start can also make a perfectly viable SP game too.
I prefer playing my games in coop when done right, because I can. One of the reasons I have a hard time playing PoE is because, despite being developped with the Baldur's Gate engine, they didn't authorize coop. ( well and since the game isn't that good either. I played some crappy games that were lots of fun in coop so PoE may have gained something there ).
I'd swear there is a strong anti-coop/MP vibe coming from a lot of gamers, maybe because of the rise of competitive esport and MP-only based game, streamed to death on every channels of the earth. Call of Duty, Starcraft, League of Legends / DotA, etc etc... Sadly there also is a strong anti-SP vibe coming from multi-players, like "nobody cares about the SP campaign in CoD or Starcraft2 lol noob". Which is stupid too, really.
I perfectly understand realtime vs turn-based though. One isn't better than the other, but it just offers a nice refreshing change going from one style to the other.
I remember the last game in the soulreaver saga, SR: Defiance, essentially being both SR3 and Legacy of Kain 3 - it was fun they were able to conclude both stories with one game.
