And what do you thing are main reasons for significant decrease of user base?
Isolated issues are not single handedly going to change things...but I think overall addressing issues helps. Not addressing issues hurts. That is what I think details the difference between hattrick and BB. Although I think BB is waay better/funner, hattrick does this thing where they constantly implement changes and you get this feeling of constant improvement. It seems to be working for them. So even though I think BB is the better game overall...hattrick is much much more successfull...and that has put the money in their pockets to continue to develop...which in turn gives them more resources and so forth.
