A good game, not a good Doom game.
No. Even based on its own merits it's just alright.
-Simplistic level design.
-Pretty art direction but a one trick pony. There isn't much variety. Seen the first level you've seen it all (aside from the two surface walks and hell. Hell is also way too short, but that's for the best since it's p. boring).
-Weapon design inconsistencies. Some weapons are great (chaingun, plasma), others feel like shit (pistol, shotgun). How'd they make a bad shotgun. It also has super RNG elements to it which is weird. Also where the fuck is the super shotgun are you kidding me. Yes, the expansion has it and its great, but that doesn't count. Should have been in the base game if the default shotgun is so bad.
-Has nothing that sets it apart from any other shooter except the graphics for its time.
-OK combat. But that is pretty much all the gameplay is; just ok combat over and over and not much else.
-Somehow for all its trying (darkness & lighting, pretty graphics, sound design, everything), it's not scary in the slightest.
-Challenge. The game isn't super easy at least but it doesn't demand much from you at all.
Interestingly enough there is one feature that sets it apart: this was the first game I ever noticed a hit indicator/marker (crosshair has a red fill when hitting targets). I guess the computer interaction was also cool.
It barely tries anything, barely has anything that sets it apart. Name a impactful level. Name a memorable gameplay feature. Name a interesting story moment. Was sound design incredible? No, it was just OK. Was the atmosphere amazing? Nope, was just OK.
Someone posted the metacritic user scores. 7.7 is probably even overrating it. I'd just say flat 7.
