Doom 2 is just more doom, but never hits the peak of the first. Sure there is a bit more enemy variety but the new enemies don't feel particularly great and end up leading you to hide. more often than not. The maps also seem like a step down. Jumping into hell in the first game still had an impact on adult me with no sort of nostalgia, while here half the time I ended up walking around a puzzle map trying to progress. That added onto the fact that this game either felt like a drag or was not properly set out, made the last few areas a slog. You would think that a level that starts you out by fighting two of the previous game's bosses at the same time would be a penultimate stage but really sits 2/3'rds of the way through. Realistically If I was to play some more doom, between the two I think I would pick Doom 1 99% of the time.
