This game was so mind-blowing when I played it on Saturn, bought at launch.
The level design is still holding up and the atmosphere of being alone and discovering places that no one visited since centuries was really something else.
It was also tough as hell, especially considering these fucking save crystals which disappeared when once used. I also liked the puzzles a lot, although a lot was finding the right keys for the right doors.
And I will never forgive the bad ending - this is all they did for an ending after creating such a great game?!
I am still mad at Sony that they bought TR back then - I really would've liked to see TR2 on Saturn. They already pushed the hardware like almost no other game with its 3d world and scope and I can only imagine what they could've done with a second Tomb Raider on Saturn if money would not have been involved.
Edit:
What? Seriously? The video posted really looks better than what I remember and what the PAL version looks like on Youtube. It seems to be something dark10x could do with a DF Retro! Perhaps I will take the time and try to get both NTSC versions and try to run them with SSX and make comparison shots.
Also this is one of the games I would really like to see 3d accelerated with yabause which seems to not gain anything from the amazing work with the Saturn code tree of mednafen, sadly
