The Official "Help me!" Thread

[Pandadice]

I need help identifying a video game I have only vague memories of. There's this PC game I played when I was really young that I would love to find the name of.

I don't remember much about it, but I'll do my best to provide as much details as I can.

'90s PC game. It was 1st person view.

I remember the first level took place on this futuristic looking building -- white walls, computerized doors etc. (I liken it to some of the sets in The Fifth Element. Or perhaps I'm just thinking of The Fifth Element and using it to fill in the blank in my memory).

It was about time travel or something. I just know that at some point (after beating the first level or something) you got in this room and it was a time machine and you could go back to prehistoric times with dinosaurs and junk. And that is about as far as I ever made it (I seriously played this when I was like 7). And I don't remember what exactly, but when you got to the prehistoric times there was like a T-Rex or meteor or something that always killed me.

I don't remember if you have a gun or shoot things or if there are enemies in the futurist building, but I do remember I found it difficult. So maybe there were enemies...

edit: I've been informed that I am probably thinking of Myst
