Oh, and now I also know why I hate games half of the time.
HLTB (How Long To Beat, but yeah, I know it looks like some sort of acronym about people's sexual orientation

) says Transformers: War for Cybertron takes around 8-15 hours or so for all 10 chapters. I'm now just starting chapter 7, and I'm already at 16 hours for the previous 6. That's 2.67 hours per chapter. Estimated finishing time is 26-27 hours. No way you'll beat this game in 8 hours when playing it for the very first time.
Reason? Large encounters and boss-fights; especially the latter. There is ALWAYS some sort of surprise. Get the boss down to 75%, and something unforseen happens which kills you (almost) instantly. He has some sort of attack, or defense, or some weird shit happens and he changes his patterns.
Repeat that at 50%, 25%, and sometimes even at 5%, and each time you have to start the boss-fight over again, until you know all the patterns and surprises. You can defeat the boss in a 15 minute fight or so (if nothing goes wrong), but to get to that point, you'll have to do it 4-5 times, and the boss-fight will easily take you 1,5 hours in total, on top of the chapter time.
Damn.
