I don't get the game rushers.
I enjoy my games slowly and take my time exploring every aspect and view. If I find a nice spot in a game that the artist have used a lot of time creating, I just stay there for a while and admire the work. I admit that I do get frustrated sometimes and just jump and shoot level through as fast as possible, only to regret it later.
It's not getting to the destination as fast as possible that counts, it's the journey there.
Now, for your question, on a single play I've noticed that anything over three hours is starting to numb me, so that I just start rushing instead of exploring, so 2-3 hours normally.
If playing PES with friends, anything from 2 to 10 hours, really.
Theres no rushing through this game. This game is simple. You go right through it in that little amount of time b/c its so easy. My 8 year old nephew could beat this game in no time to. Just because you fly through a game, doesnt mean you didnt enjoy it. I enjoyed the kong part, theres nothing really to enjoy from the first person view part b/c its the same boring thing again and again. This game is just a ahchievement leech period.
