Fantastic. Forget FALLOUT 3, which I personally think is a game of poo as it is nowhere near MAD MAX... but THIS IS!
Yes it is huge, yes it is scavenger country, yes you make everything, yes there are enemies all different shape and sizes, etc.
I have only been playing a week and updates are coming out daily, of which I have seen in game improvements. The game does have its faults but they can be massively overlooked due to the ambition. And with true MMO starts the game is often not finished properly EVER!!! And the faults are not serious and mainly you can see being fixed.
The 3 online reviews I have read have big issues which I can happy say have been fixed, and when an update comes from them in a month, you will see this game get a high score.
What you have is a great game that will just SUCK you in to the world. A refreshing change to the MMO with realism biting with a great CCRRRRUUUNNCHHHHHHHHHHH!
