Not an MMO, Not many of us really play these any more, all far to busy BUT..
Need a game to play online with folk on a regular basis, next Command and conquer style game or more likely the next big FPS.

I know we have tried a few times with things but picking an existing game seems to not pan out, if there is a game that a load of us like the look of and get on release and all into it at the same time that may work out?

Bacon just mentioned COD Modern Warfare 2

Modern Warfare 2 as expressed already.

If you want something now, COD5 is on special at Steam for £15 atm, could be worth a buy, or get COD4 thats a good game to

You also have Wolfenstein, Operation Flashpoint: Dragon Rising, Borderlands (MMOFPS), and Jumpgate Evolution ill slip in, cus its apparently instant action space flight mmo type thing but it is Netdevil (think Auto Assault, we know how that turned out), we will have to see, but looks good. Plenty more MMOs but you say you dont want them, however im sure there will be a few accessible ones this year to cater for the masses of more casual gamers.

And there is sh*t loads more. Oh and Battlefield Heroes, Cartoony, new approach.
