Please get nervous and prepare to die.
I like games where you can create big crazy situations, and I like having to learn to adapt in chaotic situations. I like variety, and lots of it. I like lots of player interaction. I like brain-burning, but I don't care for chess, as figuring out the best move makes me feel like I'm doing computer work instead of thinking creatively. I also like theme over abstract, even though there are excellent abstract games out there. I like the balance, emphasis on skill, and quick play times of Euros, but the lack of player interaction is often disappointing. I am comfortable with random factors in games so long as skill prevails. Done well, randomness adds more variety and interesting situations to figure out.
So, I don't have any 10s yet, although that may be rectified by playing more games. Due to my pickiness and desire for variety, there simply isn't one game I have played that I always want to play.
Why I like a couple of my top games and why they aren't tens:
Magic - Tons of crazy situations, adaptation, player interaction, and creative thinking. Unfortunately, there is the mana screw: you randomly don't draw your resources so you effectively can't play the game and you lose no matter how skilled you are. I also strongly dislike the collectible nature of the game, where you don't know if what you are buying is what you want.
Dominion - Adaptation, variety, creative thinking, but I find the only enjoyable player interaction is competition for desirable cards. The curse mechanic *is* kind of interesting, but I don't like it because it isn't about figuring out interesting counter strategies so much as it just junks up your opponent's strategy, regardless of what it is.
Hot list is new (to me) games that I'm excited about playing.
