I honestly prefer the MIDI rock that some would call cheesy, but I can appreciate the scary tones as well. Much like the previous console ports the game forgoes the MIDI rock tunes for full-on ambiance and scary sounds. A couple were added including the nightmare imp and a new final boss, the Mother Demon. The game features all the same enemies, with a few removed (like the arch-vile, which makes me glad). All the weapons are there, the chainsaw, pistol, shotguns, chaingun and so on. Going along with the previous console ports, Doom 64 hits most of the same notes as the original Doom but with various changes. Originally titled Absolution, they went with the much less cool name of Doom 64. However, when it came to the Nintendo 64 they decided to not just port the game and go with something more original. Midway handled the console ports of Doom to the Sony PlayStation and the Sega Saturn.
This is why they were very open to the modding community, and very open to licensing their engine to other companies.
The guys at id Software felt the same way, they wanted more Doom even as they were making it. I love to get more Doom whenever I can, and thanks to all the mods and addons constantly being created that's never a problem. I absolutely love the Doom games, it's a close contender for my favorite game series.
