Guess I should comment on these as well then
1) The Legend of Zelda: Ocarina of Time
Vilkku approves.
2) Resident Evil 4
Never played it, never actually heard that much about it.
3) Super Mario 64
This could very well have been on the first place if you ask me, it was a revolution when it came out and it's still extremely awesome.
4) Half-Life 2
A great game no doubt, but does it deserve to be this high up?
5) Super Mario World
Best side-scrolling Mario, awesome game.
6) The Legend of Zelda: A Link to the Past
My favorite in the Zelda series, but I'm still a bit surprised to see this one as high as in the Top10.
7) Halo
This is also a game I like a lot, deserves a place in the Top20
8) Final Fantasy XII
We got the wrong Final Fantasy here, boys! Why not VII, VIII or IX?
9) Tetris
When you think about the time when it was made (there were no consoles around back then), it's a pretty big achievement, and people still play it today.
10) Super Metroid
The mother of all adventure games if you ask me, this should be higher up, but at least it made the Top10.
Conclusion: Well, it was a vote, which does not surprise me. I tend to agree a bit more when only "experts" are making the lists.
