I've never played Unreal Tournament before, but now I see how impactful it is as a "genre-defining" (or as one of the games that did that) game. I wish I was there when it was still booming.

And reading this I feel so lucky to have experienced Metal Gear Solid, although I was beyond terrible at it.

One of my favourite games from the 90s is Metal Slug. Although I played it in the early 2000s, not in the 90s (so did MGS, and some other 90s favourites). It was a super fun game for me.
