Player introduction and player retention = the two biggest problems for TFW. It has always been that way, unfortunately, and without some serious investment in the game, that is not likely to change.
For those of us who overcame the initial problems we all saw what a great game TFW is. DeVadder, if you have a look at old forum posts, you can see the numerous suggestions that have been made to try to make TFW a better game. jed created TFW and made some really good stuff to keep it going but in the end it was not to be. Altren and Grug also did well in keeping it going but so far it still lacks players.
I have always thought that TFW has some serious potential. Alas, it takes money to realize that potential and, again unfortunately, there never seem to be any around.
But one can always hope, eh?
