This doesn't prove IW was lazy and didn't finish their game and/or check for bugs/glitches because technically they did finish the game and technically they did have beta testers look for bugs and glitches. I would really like to see you make a better game than MW2. Actually try making a game without ANY bugs or glitches. It's pretty impossible.
Wow, way to overreact to what I said... And no, they didn't really do a thorough check for bugs and glitches, nor did they have a thorough beta. if they had, the javelin glitch, many of the elevators, this new nuke glitch, the pavelow glitch, etc. would probably have been fixed before the game even came out.
And, no, they did not technically finish the game. There are unfinished game modes on the disc that they hid because they weren't complete.
And don't pull that "I would like to see you better" crap, as I'm not a game designer. Of course I wouldn't be able to do any better.
