I just took out the second mark, and so far I've not noticed it getting repetitive. I think it's because if I'm getting bored of swordfighting with guards, I like to take to the roofs and stalk archers, or if I'm getting bored of wandering the streets, I exit the city and ride the horsey around. But I definitely see potential for it getting really old on the horizon, so I'm staying away from that.
I do have one minor complaint about the game, though: At the beginning, when the fortress is being attacked and you are standing at the end of that plank thingy, why do they stop the action when you are told to jump to show you how to jump? Why not give you plenty of jumping prompts earlier, so that when he points to you and says "Jump, you crazy bastard", or whatever it is that he says, you jump while the cutscene still rolls?
Kinda dumb.
Dew please.
