I hope the gameplay-design will be well handled, if it has to be some kind of stealth missions (probably thought, as i doubt going in a building, shooting all around to steal something would be a genius idea, if wounds are as deadly as they're supposed to be.), or to use the "pickpocket" skill or to sneak inside a building.
Gameplay is very important, not to say it make the game itself, it has to be fluid, and very responsive, mostly when sneaking (even more if the AI is smart), controls have to be thinked about to make it very intuitive, because sometimes you'll need to react pretty fast, and honnestly it's funnier to die because the game is hard than because the controls are awkwards.
