I find it okay, as long I get really explanation how the duck he got there
... Sadly as you said: "
"Oh... my... fucking... god i have lost COUNT on how many" times that thing doesn't get explained...
I say that my CS has also similar system -> You wake up, you are in fucking table, you are being fucking cut and you lose concious. And now you gonna get to know story, how the fuck you got on that table.
In some sense, you can indeed do as well: "You are that dude and you go into that place to discover that", etc... It is awesome, but sometimes it can be rather boring or worse then what OP topic said
