Dead Space 2 comes to mind.

Also makes me wonder how different/longer/better the Campaign of Assassin's Creed and Uncharted would be without the need for MP, and instead focus on the story and gameplay of the SP mode

I disagree with Uncharted.

Uncharted's MP is super fun, both 2 and 3.

Uncharted 3 is even supported on Fraggednation and gamebattles.

This is a common thing said by many solo-gamers. They don't appreciate the idea of playing with other people in their games. If I could, I'd get Co-op in all my games.

Since playing with friends is almost always better. It's just up to the developer to prove it to you.

Oh and for the picture used for this article, Mass Effect 3 has a fantastic multiplayer. I've spent 282 hours and 39 minutes playing it, and I'll continue to do so now that they had that recent huge update. Not to mention ALL the MP DLC was/is free. Talk about doing it right on your first try.

Personally I feel that the market already has plenty of good multiplayer games, and it used to have plenty of good singleplayer games as well, but now all the good single player games are adding multiplayer modes and in most cases it hurts the singleplayer experience.

I don't expect it to change though, so instead of letting it get me down, I have simply started to research each game purchase to make certain that the singleplayer experience is worth the full asking price of the game. If not I won't buy the game, or I will wait and pick it up when it hits the bargain bin.

ME3 had a surprisingly fun multiplayer mode. I play it still occasionally, and after just buying Bioshock 2, I can certainly say that more than enough people still play online.

It's nice to have a break from the campaign and I think that is why most people enjoy these multiplayer modes. Sure, some don't think highly of them, but still...they can be fun. A lot of these games never had a chance at knocking out the big multiplayer games though.

If the multiplayer is good then it is justified. Who cares if it is "needed" ? What does that even mean? Same thing with so-called "unneeded sequels". The question is whether the sequel is a well made, fun game, and worth playing not what some silly self important "game enthusiast" arbitrarily and unilaterally decides is needed.

Yes, this applies to Bioshock 2, the upcoming X-com real time third person squad shooter thing that used to be an FPS, and to stuff like Skylanders and the painkiller remake.

If you don't want something then obviously, don't buy it.

But don't go telling the industry what it is allowed to produce and sell, and don't go telling audiences that they are allowed to want and enjoy just because you have some irrational hubristic need to publicly disapprove of stuff and get all snooty and bossy about it. Odds are that if you didn't want it then someone else did. So just let them be. Stop trying to guard your favorite little sacred cow IP's from being expanded or changed a little just because you haves ome weird ideas about what is supposedly necessary.
