Meh, it was to be expected. Some people cant take any criticism whatsoever of their precious game. More than anything, I laugh at the predictably prompt arrival of the MGS defense crew.
I think Act 1 and ACT 2 are the best because of the gameplay.
ACT 3 is cool because it has an awesome chase sequence, but overall is super weak from a gameplay perspective. ACt4 is cool because it's shadow moses. Act 5 is shit because there's barely any gameplay.
Gameplay wise, this is not the best game of the year at all. Grand Theft Auto 4 has more gameplay in a third of it than the whole of MGS4, that's why it pisses me off when i read that official thread.
It's not that i don't like MGS4 better, i do, it's my fav game this gen, but it's not the best game, not at all.
