I can't remember any COD4 or Halo3 issues, pretty seamless really. Only problems that we have had were due to the Live service. Also I like games to matchmake for me on a rotating, party, basis.
Early on there was loads of dropping games etc with COD, Gears of war had issues at launch as well.
The trouble is if you played ranked then the whole idea is not to let a party stay together for boosting. I'm pretty sure gears of war dropped you out after a ranked game as well.
The trouble with COD match matching is in normal play you can play 6v6 say Overclockers. Unless you play private and as soon as we tried that everyone left because they were not levelling up.
I like the way you can still fill a room full of overclockers and still play the game as normal. It doesn't have to be ranked.
I don't understand why it seems to be one game or the other. There's sod all on the horizon shooter wise til what Gears 2? No reason why you can't play and enjoy both games.
As I said people keep making out Cod 4 was ground breaking, it brought nothing new to the genre. The perk system was ripped straight out of the star wars game.
I regret selling COD though, should have kept it. I will by it again but I cant find it for less that £35. I will go to £30 max new and take the hit
For me COD didnt need new maps it need more customisation. Snipers off, Grenades off. Two or three of the maps would be like playing a new map if you could do that.
