I'd much rather have modes like gun game added. Not infected unless they barricade parts of the maps of, like treyarch did with wager matches, reason being is all people do is camp behind counters or on ledges, so it's impossible for the infected to get them, it's quite sad people do this in a private lobby.

But yer 3rd person was horrible in mw2, for the simple fact people would sit at a corner, and be able to see around it.

I never played 3rd person in mw2 but I would give it a go now in mw3

why is sabotage still a playlist? maybe because its been in the game since COD4 and maybe before that. they only tried 3rd person in MW2 and it was only 4 gametypes 3 of which were cut out leaving only team tac. and it did not make a comeback in BO or this game. they wanted to try something new in MW2 but then saw how unpopular it was against the others so they didnt take it any further.

that is why they didnt bring it back. it is NOT that popular against the other game types. and you have to remember that they not only have to think about what is more popular but also the space in the playlist. they cant just add something to try it out, they have to think about whether or not it would be popular and if there is enough space to put it in, like drop zone.

i played 3rd person for a laugh on a private DM and i thought it was actually pretty enjoyable ^_^

I wouldn't mind a 3rd person playlist.  A lot of my friends and I used to play 3rd person quite a bit in MW2 and there are actually two who didn't buy MW3 solely because of the exclusion of the 3rd person playlists.
