Dishonored - Colantonio and Smith Interview @ Sneaky Bastards

This interview with Arkane's Raf Colantonio and Harvey Smith is about the stealth genre but obviously, Dishonored gets several mentions:

What are your thoughts on stealth gameplay being included as one possible path or playstyle, as opposed to the main focus of a game?

Raf: This is the approach we’re taking with Dishonored: you can chose a stealth approach or attack head on, or in combination. My personal thought on this is that it supports simulation and player choice, which is always a good thing from our standpoint.

Harvey: One could argue that the game is stronger with a pure focus on stealth, but like Raf said we find it more interesting when a range of options present themselves. To us, the most interesting games constantly present the player with inputs and outputs that work in as many general cases as possible: gradients related to movement, powers/weapons, morality, and enemy perception. So many things can happen in that environment that the end result feels like something the player authored. Personally, I think analogue awareness would add to many games. If I play a zombie apocalypse game or a shooter, I really want to be able to play cat and mouse. Far Cry 2 is one of my favorite shooters of all time, for instance.
