Greatest Chessgame?

How do you judge art? It´s hard, if not impossible to pick a single game as a favourite. Every great game has its own unique personality, its own temperament. So which game i value over all depends alot on my mood.
That said, Botvinnik vs Capablanca 1938 is a gem. How can this combination not evoke admiration in the chessplayers heart;

I think Kasparov vs Topalov was one of the greatest games in modern history when Kasparov sacraficed a rook

this was a good game (its tough to learn for it, but lever ideas from Anderssen)

What's so great about that game (Tal-Keres)? I mean, it isn't bad, but I wouldn't put it even neear the top 50 I've seen.
Well there was no brilliant moves but the game was brilliant, and your right, but they almost made the whole list of best games only this one was left ;-)
