>>11807914I kind of get you, but at the same time the first Doom to me, it feels like it's not quite enough in all that it is, the monster setup BADLY needed the new guys in Doom 2, at least a few of them, so Doom 2 adding a lot of refreshing complexity and variety onto the first game's gameplay.
The Super Shotgun was a good addition to even things out with some of the new monsters, and Doom 2 has enemy encounters where you might actually really want to have the BFG9000, as opposed to the first game where it's just kind of there as a secret, but there's never a time you feel that you actually gotta have it.
It pretty much is an expansion pack, but at least it's a good one.
If I'm gonna criticize it for some things, it's that it relies a bit too heavily on brown and tan textures, reuses some music tracks too often, that a few of the levels are kinda weak, and that the game would probably have really benefited from having its levels divided up into episodes like the first game did, complete with the intermission maps.
The intermission maps woulda been cool, and the difficulty level of the game would have been stronger if you got reset once or twice along the way, so that you don't always have your cool toys. (Plus, there would have been space for one or two more secret levels).
Icon Of Sin isn't perhaps the best end boss ever, but he's also an improvisation to try to have something different at the end of the game, since they didn't have the time to have an all new monster model made (a lot of the new monsters in Doom 2 were unfinished ones left out of the first game).
