They changed the monster designs so they all look like someone's hurling tremendous turds in your face, the weapons look crap, ...
Oh yes, and some of the monsters had large and obvious anus holes, which I have always wondered if it is meant to be symbolic.
I couldn't resist, the quote just seemed to fit so well. The connection between Doom and feces seems to be made really often, especially at DW.
Yeah, shitty game, with all that brown, and all those brown, shit-colored monsters....
Yes, but the new atmosphere works here, because it's not "Doom 1 but dark and slow with ambient noise", it actually delivers new spritework (that on 2nd viewing, with a real N64 on a CRT screen - looks damn good) and levels that are granted, a bit repetitive, but aren't just trying to be more of the same from the previous games. In some instances the level design felt very Duke3D-ish. The game dared to try a slightly new approach, and I feel it worked quite well, even if it wasn't the golden masterpiece it could have been.
Also, gameplay was even slower than on the Playstation..
Doom 64 always felt like the "real" Doom 3. Doom 3 is good, but doesn't feel that much like Doom - but that's another discussion we've all had at one time or another, so I'll leave it be.
This is the problem with Plutonia in a nutshell.. It gets old. It definitely doesn't "suck" but TNT felt fresher for a longer time. Oh and the lack of new music (not even 3 or 4 new MIDIs?!) blew arsehole as well, it could have at least recyclted some of the TNT tunes. I've already heard the E1 songs before, give me something fresh for my money, damnit!
My memories are finding it unplayable on co-op due to constantly being hit by Chaingunners.
