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.
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.
I started playing Hattrick in the summer of 2002 when a friend, who I played "Fantasy Wrestling" with online, told me about Hattrick. I made many mistakes in the beginning. At that time there was no such thing as mentors or beginners' guides. So my very first club was bankrupt after only a few weeks. Luckily, I was able to restart with a new club shortly after that and then I did a lot better.
I am one of the old users who likes to do my own research to learn how the game works. I like that this is a thing in Hattrick. Not everything should be mentioned in the rules. I also like the federations where you can have some real tight friendships. More than some friends call Hattrick a forum, with a soccer-game attached to it.
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.
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.
