His main point is:
I think 2010 is bad;
Therefore it's dead;
The only way it can be alive and good is if it had good multiplayer.
He supports this by subjectively saying:
The mechanics are poor;
The game is played and catered to children because it's on console;
The studio just pushed the game out to earn coin.
If we objectively look at it:
mechanics, aside from the delay, it was usually met positively within a greater consensus;
The game is not played nor is it catered to children just because it's on a console.
The studio most definitely wanted to earn money but they wanted to earn money from doing a good job, not a half assed one.
I mean even the claim that 2010 is not an Arena FPS is also wrong. If being wrong was an artform I can say that these statements damn well perfected it.
