I do this in a roundabout way by like, taking the developer-intended/assumed first-time route or playstyle through games I know the alternate/secret/spicier routes through/playstyles of. ////
If i’m feeling like an extra weirdo, i mix that with my habit of half-pushing the left stick/holding the walk key and slowly panning the camera around like E3 demos do. Like, instead of playing it for the first time myself, I’m demoing it for an imaginary person seeing the game for the first time, mainly in immersive sims i.e, Dishonored or Watch Dogs 2, where i think about the most dramatically interesting chain of actions & events I can pull off to solve a thing. Much of my fondness for Mafia 3 comes from it being the game where I had an actual person watching me do this for most of it.
Listen I’ve just been fascinated with how that Watch Dogs demo felt to watch back in 2012 and it’s become a real problem okay
