I only learned about this wide world of gaming in late 2005. Before that I had enjoyed traditional card games like Pinochle, Hassen Pfeffer and Spades, as well as chess, and occasionally risk or clue.
I don't game nearly as often as many on this site. Maybe one day a week, or even a few days a month. Occasionally, I push for more, but I'm trying to mold gamers out of my friends, and it requires a good deal of patience sometimes.
I love games as a medium weight mental exercise. So I prefer games that lean towards control over chance elements. Theme and nice components are secondary, but important and can notably affect the game experience.
Since I don't game frequently, it's taken me over 5 years to come to realize the kind of games that I most enjoy. I'm not inclined to dislike games usually, although I'm starting to get a better sense of what I prefer and would rather not play. Expansions I rate according to what the base game becomes by using them.
I rate according to bgg guidelines, and I expect my ratings will change, so I have few 10's right now. I tend to grow tired of things over time, so it's taken a while to see which games really prove themselves (and will continue to). Go may be the perfect game, and I could probably enjoy playing it forever, although I don't always want to play it and have yet to become any good (it's still a 10).
I'm open to just about anything from abstracts, to Euros, to card games, to wargames, to dexterity games. I recently updated my Hot 10 to reflect my top 11-20 games.
