DOOM II
Genuinely great game. Great levels, great action. Genuine classic. My only thing is im not a diehard DOOM guy so I didn't know about the sprint button, which you need to get a key on the second stage. what a nightmare that was.
DOOM
Much like Donkey Kong Country 1, Sonic The Hedgehog 1 and many other first games, its an amazing tech demo, but the sequel is just does it better. Not enough ammo and the keys are too hard to find.
DOOM 64
I'm not far enough into this one to give my definitive opinion but so far, this feels like another Sonic CD, so few people played it that people have tricked themselves into thinking its good. This was actually the only DOOM game I ever played for the longest time as I was a console guy when I was younger. I never got far into it as I played this after I played mario 64 and zelda so the graphics kind of confused me.
On the bright side, they fixed how insanely dark and hard to see the game was, on the other hand, theres so few enemies, the gun animations are wimpy, the enemy animations barely react to you shooting them and these early levels are a bunch of boring narrow corridors.
