Stealth games tend to come in two flavours. Nowadays most are systemic playgrounds, in which players are presented with a range of options for how to deal with any given situation, and errors are forgiven after the few seconds it takes a guard to decide it was probably rats. A handful of others are more rigid, with only one correct way to play, and each stumble from the shadows punished by death and loading screens.
I like both of these kinds of stealth games, though I prefer the former. My frustrations with Wildfire can largely be traced to not knowing which kind of stealth game it’s going to be in any given moment.
