I was talking to a friend about this notlong ago and he said something intresting.
They always come back. Once peiple get hooked to it they come back to kill some more time when they are bored.

I noticed a slight drop of activity from my market sales a few months ago, but now it looks like its coming back to normal. Summer is coming soon. In summer there is always a boost of activity.
The problem is that a very small percentage of players stick to the game for more then a few months.
I think this game is slowly dying and loosing members.
Just look at how many people are online every day. When europe is playong servers are few and empty. It used to be more full.
When america is playing the servers are more decend and more people are online.
The less peiple that play toribash the more boring is the game getting and vice versa.
Overall i think it will still be here for a few more years but it wont be like back in the days, less people wil be on.
