Welcome back to the game! It is awesome to see returning players.
We see the most activity on the weekends during main EST times (12PM-8PM-ish). During that time you can find quite a few players on - but not as many as back in 2013. We are trying to bring this game back to its glory days and it is when players like you come back to join us that that becomes more possible.
We do have an update coming out for this version of the game, but as of yet we do not have a set time - but I can promise you that it is going to be fantastic!
As for FHU - they are an independent game from us and have a completely different moderation team and servers. You can find their information on their website.
I hope you have fun being back with us!
