All games don't need multiplayer and it's still only wasting resources. Especially if the game turns out worse in the end like games listed here. You say why not spend more time but I'm guessing you probably haven't heard all of the complaints about the Japanese game industry.pure.Wasted said:"For sales" doesn't have to be a bad thing. It means I want to come back to a game over and over because it has replayability.80Maxwell08 said:Except he only says they should do it for sales. Hence tacked on. Especially since his examples were 2 games that don't need it at all. Guess what games need money and if a game is supposed to be single player focuses I don't want it to have resources wasted on some multiplayer that's only there for worthless marketing.pure.Wasted said:LOL @ every single response so far talking about tacked on multiplayer when the man clearly states he's not interested in tacked on multiplayer.
Here's an idea. How about developing a great single player game that has *gasp!* a great multiplayer?
Pokemon should have gone massively multiplayer (and I don't necessarily mean MMO) a very long time ago. Not just for endgame lvl 100 vs lvl 100 competitions. There are so many opportunities to insert meaningful multiplayer into the singleplayer experience so that the two are seamlessly integrated and help each other, but no.
Dark Souls sort of has the right idea, although it's a bit too encouraging of griefing. Then again the singleplayer is all about getting griefed, too, so it's really not all that different...
You're approaching the problem from the wrong angle, I think. You're assuming that the developers have already come up with a concept that works flawlessly for a single player game, and then resources must be diverted at the last second to add some multiplayer mode. But that's backwards. Why not spend a few more weeks or months designing your game so that the multiplayer is a natural extension, and doesn't take all that much work?
Take Diablo 3. The multiplayer is essentially the singleplayer + other people. Except Arena PVP, which can't have been all that difficult to implement, honestly. Look how much replayability and fun they added to the game by doing absolutely nothing except adding multiplayer. Now, did it help that they knew they were going to do this, and so created battle systems that worked for singleplayer/multiplayer interchangeably? Absolutely.
One of the complaints they said is incredibly strict budgets and time limits. So if they tried to put multiplayer in then it's basically assured the single player will suffer to some extent. Also considering the devs had to come out and say they were designing it with multiplayer in mind rather than people knowing this I would say your last example is a bit false.
This still doesn't change that not everyone wants some random multiplayer in there just because. Plenty of people buy single player only games if the single player is good.
