You did it in 15? Took me 20 heh.

Anyway, I understand that games are multiplayer focussed but it's really just a way to avoid creativity in your game design. If you make a 5 hour game and just focus on good multiplayer gameplay then you only need to come up with 5 hours of solid plot and artistic design. After that you just throw together 10 multiplayer maps, solidify the gameplay, and viola you just made a game for much less effort.

I suppose there are some games I would make an exception for if they just had massive amounts of creativity crammed into that short single-player or if they had a lot of replay value, but even then it's unlikely I would buy it at full price.

Yeah, Halo's is probably alright.  Over 10 hours and at least it offers co-op.  I'll accept co-op as a way to change the experience.  At least it shows some effort put into extending the life of the campaign.  Still, 10 hours is the low end of what I consider acceptable.  Ideally games should be 20 hours plus.  

not that i care about single-player, but 5-6 hours is just shitty, activision is the new EA confirmed

I still think Zelda: TP is the greatest game so far this gen. 40-60 hours of pure fun.

That is pretty short...although surprisingly, I totally forgot COD4 had single player...the multiplayer in this game is superb, and will be worth the price for many I'm sure.

 To many, Elder Scrolls 4 would take the award, certainly for length

Sure it's longer, but it's nowhere near as fun, at least not for me. I couldn't get into ESIV at all.

 To be honest, I did not get into it either, after getting out of the sewer, I had to walk for half and hour to get anywhere, it just didn't appeal to me

still most console buyers are single players ... to leave them with an under 10 hours sp mode is just not right

and it's in my opinion even worse ,that critics will give the game 9-10s even though it has such an obvious shortcomming

they should make seperate reviews for multiplayer and singleplayer to make it fair to the readers

Halo 3 taking more than ten hours? Me and my friend started it around 17.00, and finished it by 02.30, including 30-60 minutes of taking breaks for various reasons. Talking to my other friends, it seems like we were relatively slow with it. I'd definitely call it too short to receive a full score, even with the superlative multiplayer.

I wouldn't call Twilight Princess a current gen game, as much as a last gen game that got bumped way, way too far. It's still awesome, but a Gamecube game nevertheless.

 Same.  Not to mention everytime I'd open a door, I'd get arrested.  It was really annoying, so I just quit.
