Hmm, maybe I'm thinking of something else since I might be referencing the real 1st stage and not the prologue, sorry it's been a while since I last played it, though most people did really like that beginning.
The opening was thrilling, emotional and perfect. After the opening act, the game gets boring I agree, but the first 15 minutes, especially if it's the first time you're playing it, is perfect.
this has got to be a joke post, I thought the game was actually gonna be quite shitty during level 1, but the game did a complete 180 starting with level 2.
