before starting this review when i first played Doom I & II i didn't have any motion sickness and whatsoever and i had a really fun time,with this particular title however the motion sickness really got me and i'm sad that it killed most of my enjoyment because it's a good game and interesting take on Doom that i think worked in some areas,sure it's not as loud and engaging as previous Doom games were but Doom 64 makes up by having very eerie atmosphere with good consistent level design and great sound design as well,it's just a shame that it's not a title i will looking forward to play again in the foreseeable future.
