I love Hattrick because it's simple. It is not taking much time to learn the dynamics, but you can tweak it forever. I love Hattrick because to me it is like Subbuteo or Risk. It is simple to learn but hard to master. It's still exciting to wait for 90 minutes to see the result of a game, four months to see the end of a season. I love Hattrick because it is possible to set goals for several years, to see your team growing up, to learn the names of the players, and to build memories about them.
What I like about the Hattrick community? Everything. I like all the help you can get in the forums about the game, but also for everything else it gives you in everyday life. Hattrick is my favorite social network.
I was ranked 1st of all teams in Botswana after the first league round, that was one of the best achievements for me in Hattrick. Of course there's a lot of luck involved there, but hey, they're never going to be able to take that away!
In HT, my biggest achievement is to be the assistant manager of the U20 national team of Suriname. And of course also, when my dream came true and I reached the third division with my own team!
One reason I play Hattrick is because I like the cyclical nature of the game. You start with an idea about what kind of team you want to build, then you train long-term (up to 3 years in real life!). While you build, you can test and try to comprehend the aspect of the match simulation that you want to master. I also like the tactical choices you have to make for each match. But the most important component is the community.
What I like about the Hattrick community is that there are real people and you don't just compete against the computers. You play against each other, but you can also help each other in the forum and talk about everything.
