You both didn't watch it then. He didn't complain about any re-invention, he complained that IW did not deliver on promises, nor learn from past experience.
They stated that they will have console support, and they did not deliver. FPS is capped at 90 frames, and since console is not available the FOV is stuck at 65.
They received massive feedback on how MW2 was a flop for the PC community, they had Blops to get further information on it, but they still kept their heads up their asses and pushed through with a repeat of previous errors that were already brought to light.
The result was a game that was not designed for any serious gameplay. Sure, it may be fun for a casual player, but that's not what he's arguing. He's a competitive gamer, so he's stating an opinion by looking at aspects key for a competitive scene. That's also the reason why I posted a first video, which was much more laid back.
Both videos I posted aren't complaining about no re-invention, they're complaining about a lack of responsiveness to the PC community, and a failure to deliver on promises.
And btw Joe, he played for a couple hours on stream. And it doesn't take a couple hours anyways to determine if a game isn't good. 20 - 30 minutes in on CoD4's release and you could tell the game was seriously botched and needed a quick patch. Fortunately, they delivered there.
