No apparently the quicktime events are only there to use if you want extra skill points, you don't have to use them
They are saying that, but its BS. Watch the video, up on the tower you have the guy go into an "event" he pulls his leg back to kick him off the ledge.... they it says "YYYYYY", so what the hell happens if you don't press Y, he decides to not kick the guy off the freaking ledge? Same with almost all of these, he goes into an execution and pulls his arm back ready to swing and cut his throat, then tells you to press a button.... but you don't have to press the button.... great. What he's saying is you don't have to press B to go into a QTE for each kill... but we've all played these games before, non QTE execution means taking ages to kill everyone, while killing a stunned or execution ready enemy makes it an instant kill and probably makes you immune to damage during the animation.... and probably stops all enemies actually attackign you while it happens.... It seems incredibly basic, just pretty and very very basic.
AS Spookywillow said, just have an execution button. I have no idea why people make prettier games look more realistic then flash ruddy glowing button labels all over the screen... it looks completely absurd. This easy mode combat, hit everyone once then press whatever button it tells you to on screen... then lose control basically . It seems to be press B(which is above everyone after basically one hit) to go into execution mode, then he's already doing the action and it wants you to press a random button it decides AFTER he's basically done 90% of the action already, feels utterly stupid to me.
THese things are very cool, executions, finishing moves.... for about 5 fights, then you just get bored with being constantly out of control, it becomes boring almost straight away. Countering and deflecting in Assassins creed was great, for about 10 mins, but then it was dull as hell.
If its not significantly more complex than the video showed and significantly more tactical...which is very worrying as they said they slowed down and made the video "more tactical" to show it off, then I think it will be a very pretty pile of turd.
