Well, lets see here
- Ocarina of Time. This doesn't even need an explanation
- Eternal Darkness. This game was excellent. Great storyline, graphics and gameplay and it kept me entertained enough to play it through three times to get the final ending.
- Pokemon Red/Blue. Yes I am adding these ones in because despite their childish nature, they were fun and completing the PokeDex doesn't involving find 8 billion different f****** varieties of pokemon as the modern incarnations do.
- Baldur's Gate 2. I have played this game to death and I still love it. I have yet to play it the same way twice, although my favourite was the sorcerer class.
- Super Smash Bros. This was the highlight of the N64 aside from the blessed Ocarina of Time and allowed my parents to discover new swears words as me and bro were beating the hell out of each other.
- Goldeneye. It was kick ass for its day. You could even lag it

Finally Diablo 2 - Truly awesome game. Well done to Blizzard.
