1999, (Runoff) Game of the Year

[Machina]

I actually prefer the 'other notable games' to the main ones. I didn't play it at the time - didn't even realise it was a thing until the 2015 remastered collection came out - but Homeworld is my pick here. So far ahead of its time that it stands up well even now. Great narrative and concept, excellent music, and some very ambitious RTS gameplay.
