I don't understand this fetishization of Doom. I liked it because it was gory and pretty but I always wished for better graphics, better controls and better everything. These old shooters don't do it for me. Sure it was important at the time but I don't like how it aged and I think it's become the equivalent of the fucking Zelda or Mario in the way how hipsters "love it it'z oldskool man remember that one time your dude got low health and his face gets all frowny and bloodied?"
You're applying your RPG-drought-inflated anger on every other genre and use the same criteria and it's stupid. The best thing about Doom that I remember liking was the level design of the first few areas, then it gets retarded. I like the art direction but it gets retarded later, too. It looks like shit now, I don't like shitty sprites in my 3D FPS, I don't even really like the super fast movement, I hate the BFG and all that shit.
I don't think doom 1 holds very well gameplay wise (except maybe the first episode) compared to the sequel and most popular level packs.
people don't fetishize doom 1 specifically but doom in general including the various level packs by amateurs (many of the original ended up designing levels as a professional). The gameplay formula is more interesting and fun. It's the way you have to manage crowd of enemies in levels structured to make it as interesting as possible.
There is a lot more to be said but obviously fighting a large crowd of enemies while moving at super speed and using an overpowered arsenal and having to prioritize targets is more interesting that pop a mole shooting. Maybe you are being obtuse?
serious sam is fucking great... get lost. Serious sam just takes the most frantic moments in doom 2 and makes a whole game based on that an in my opinion it not only works, but works great. I'm not such a fan of first encounter, I'm talking about second encounter and bfe.
regarding brutal doom, it's pretty cool and fun, the haters are lame and are also over reacting. It's nerdrage caused by something stupid. It's just a slight variation on the doom formula
