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.
My biggest achievement in Hattrick so far is that I have won some titles with my second team in Bahrain and reached the semifinals of the National Cup in Italy, but I hope, a few months from now, that it will be winning the World Cup for the Italian NT.
I started playing Hattrick because some of my co-workers absolutely wanted to introduce me to Hattrick. When I finally tried, it was the Valentine's Day of 2009 … and I am still here, ten years later!
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.
When I started my studies back in 2002, one of my roommates played Hattrick. He was really excited when he explained the game to me, so I started playing. In the first year of playing, I got an HT-mail from someone who was living nearby. At this moment he is still one of my best friends. We both started playing again when we first stopped playing somewhere in 2008.
What I like about Hattrick is that there are not 248 925 784 skills that you have to pay attention to. I like that there are several (but not too many) tactics and that they all have weak points that other strategies can beat. I like that this is a slow game, it fits my private life. And that is probably also why I still find it interesting after almost fifteen years.
