The Hattrick community is colourful, it really helps expand the Hattrick world. You can find plenty of helpful managers that can help you with Hattrick and real life questions.
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.
I ended up playing Hattrick because I used to play some MMORPG in the past (like Dark Age of Camelot or Ultima Online) but they were totally absorbing and some of my friends described Hattrick as "easy and casual", and I believed it (lol). I couldn’t really guess, at that time, how much time and passion I would end up putting into this game.
One of the best parts of Hattrick, for me, is the fact that you can somehow massively relate to a bunch of fictional players with fictional names and treat them like they're real world players.
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 would say the community is the strongest reason I have stayed in Hattrick for so long. The game too of course. After having trained my players and played in the French Division 2 for a while, I started focusing on training international players to help the Moroccan team. Today 80% of the defense of the Atlas Lions was trained by me!
