I really can't believe you're moaning about things to do. That's the best thing about it - that it's actually trying to do something different.
Indeed, very odd thing to complain about. If he's not going to play the game 'properly', then that's his problem really.
But of course, the reality is that we don't know how it's going to play or what options there will be for getting things done. I would imagine it'll be a Hitman-esque system of there being various ways of achieving the same goal.
