After reading reviews and now playing the game for myself, I find it difficult to believe how the reviewer is playing the same game as me.
To quote the Edge review:
Theres the banal and unfailable linear platforming, your next destination shown by a noisy cloud of bats, which kills stone dead the prospect of any meaningful exploration. The bat cloud is itself also deeply flawed. Reach a summit and youll hear some of the chiropteran screeching that suggests an elevated handhold is nearby. Youll look up and around and find nothing, then look down to find the cloud at your feet, guiding you back to the ledge from which youve just climbed.
How is this different than the first game, when they did the exact same thing? The only difference is that in the first LoS they highlighted a handhold in a golden color. I'm sorry, but that is just nitpicking.
Another quote from the same review:
Even more brazen is the way the frequent, lengthy loading times are hidden behind endless elevators, decontamination showers and supernatural airlocks.
I admit I'm not very far into the game but I experiences the above mentioned so called 'loading times' a few times already. How the reviewer can call those frequent and lengthy is beyond me. A game series like Assassin's Creed has much more loading time between sequences or time periods and I don't hear anyone complaining about those. Aside from that, I find it commendable that Mercurysteam tries to piece the whole gameworld seemingly together and tries to hide load times as much as possible.
Of course everybody is entitled to his or her own opinions, but some of the criticism I've read about this game could almost be directed to every big budget AAA-title.
