If you play a SP only game, do you ever complain about how there is no MP mode and how that's cheapening the value of the game? No, you don't. In fact, most people get annoyed if a dev puts tacked on MP on to their SP game, telling them to focus on the SP mode more and make it even better than tacking in MP. So if that's the case for SP games, why can't a dev put all their efforts and make a highly enjoyable, full blown MP game without putting on a horrible tacked on 4-5 hour SP mode that has no replay value like in most shooters?
If a SP dev can make a solid content filled game that has no MP mode without making you feel that the value of the game has been cheapened, then a MP dev should also be able to do the same with a good MP game with no SP mode. If it's the contrary, then just don't buy the MP game. I will personally buy a game, whether it's SP only, MP only or both depending on how good the game is and if it's fun enough to deserve my money. I don't have a preconceived notion of a game NEEDING to have either a SP or MP mode for it to be good value for money.
