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!
I play Hattrick because I am a big football fan and I have always liked to play football manager games, like the German game "Anstoss" or "EA Football Manager". I play Hattrick since 2002, even though I had a break because of the birth of my daughter. So Hattrick has been with me for most of my life, you could almost call me "addicted” to Hattrick!
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.
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.
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.
