Metro also comes to mind. The highest difficulty level made both you and the enemies squishier, while also making ammo (which doubled as currency) much rarer. It played so much better that the community even recommended that difficulty level to complete newcomers.
… And then they made the Ranger difficulty a paid DLC in the sequel…
I’ll not cotton any slander against Doom of any stripe, be it I, II, Final, TNT, Plutonia, or 2016. (Note that we don’t talk about Doom 3 round these parts.)
Yes there was a doom 3 in the early 00s. It was atleast a good game great graphics fun gameplay etc. But it was more like a horror shooter instead of an action shooter like the other dooms
