Right, so i bought Dead Space 2 on the first day of release, something i have not done with a game for a long time, but as soon as i heard about it i had to have it. It didn't disappoint. Currently on my second play through on new game+ (still on Casual difficulty, after a bad experience on hardcore difficulty, decided to leave the higher difficulty levels. At least for now, anyway.), enjoying the new suits, upgrading all my weapons, etc. However, it has only just dawned on me that i haven't touched the multiplayer mode at all yet. As a gamer, i do try and experience the best games on offer, new or old, but i have to admit i'm a bit of an achievement hoarder also, so i was disappointed to discover that there are NO multiplayer mode achievements, although there are a few that can be obtained there. These are mostly aimed at the single player though. This is the main reason why i am yet to enter multiplayer, which i'm sure will cause frowns among many, but i feel there is a lack of incentive for me to do so. As you can probably tell from this, i'm not much of a multiplayer gamer (online anyway, except for FIFA), and i don't intend to offend anyone who is, just because of a lack of achievements. However, the biggest online games on Xbox all have them (COD, Halo's, Gears of War, etc), so i feel it's little bit of a missed opportunity. 

Right, because people who don't have Xbox Live shouldn't be allowed to get the full 1000, right?
 
DS2 did it the right way, by allowing players to get some achievements in single player OR in multiplayer, not specifying which. 
 
CoD is usually the same way, although I think Black Ops had one (the wager match achievement was the only one, I believe.)

Thank you Dead Space 2 for not having multi-player specific achievements. Not a fan of them.

MW and MW2 had no online MP achievements and look how the popular the MP in those games are. MP should stand on it's own without the the  help of achievements. If a game needs to have online, or offline for that matter, achievements in order to give you incentive to play it then you shouldn't even bother with it to begin with. 

I loved that DS2 didn't have multiplayer achievements. That usually kills a game for me because what if there is no community playing the game to get the achievements? I've had this problem lately with Red Faction: Guerrilla and Condemned 2; I can't get 1000 achievements because no on is online in those games...

Add me to the list of people who love that there are no multiplayer achievements, and I seriously enjoy the multiplayer. Multiplayer unlocks are achievement enough for me. 

" Yeah, multiplayer achievments are horrible. You're in the tiny minority, dude. "

Thanks for all the feedback guys, just to make it clear i'm not a fan of multiplayer ONLY achievements either, or am i much of a multiplayer gamer at all - FIFA 11 is the only game i have dedicated any time to against other players - but as an achievement grabber the lack of said achievements has so far not given me the incentive to enter multiplayer mode. SO FAR. Once i am done with the single player, i will enter multiplayer mode and (hopefully) enjoy. 
 
With regards to having to have a gold account just to 100% complete achievements in a game, it's wrong in my opinion, but this is how Microsoft make their money and part of the reason why multiplayer achievements do exist, whether we love them or hate them. I'll never get that last achievement on Sonic 2 :( 

Glad DS2 achievmentys where not MP related. Hated that RE5 had VS. achievments.

I HATE multiplayer achievements.  They ruin the fun.  For example, not being able to win 5 ranked matches in a row is making me enjoy MvC 3 less than I would otherwise.

I have to admit, putting in MP achievements to force people to try it sucks. MP focused games like Left 4 Dead etc, fine, but in game where it's a sideshow I prefer the whole 1k is SP.
