Hello there! So, I was just replaying Middle Earth: Shadow of Mordor, and decided it had become too easy with my uber powerful ranger. So I started anew and avoided anything that even remotely upgraded my ranger, sticking just to the story. I hadn't experienced the nemesis system as deeply before, for now if I saw my rival in the distance, I got the hell out of there, while having him hunt me. It was really cool.
So this got me thinking, am I the only massochist (of course not!)? Which are some of the self-imposed challenges you do to keep games you've played interesting?
