Advertisements, Subscriptions and Clicks = Revenue.
Dead or not, people still play them and still have people on the Top lists, playing Tournaments too whether its a few people or not, it's still alive and i for one have subbed to Fod for Tanx since 2007 and Im still subbed even if i barely get on, it's my way of showing support to the site for all the good times i had on here under my old alias FTW Warrior.
They profit from dead games because people like me who still come back time and time again and re-sub and play from time to time as well as others too. As long as it brings in some form of revenue it's worth keeping it there, same for the other games if they have regulars too.
Confident iv spent over 1k on subs over the years and iv subbed other people too..not just myself. Few players or not..if were here it's still revenue.
Iv had hundreds of subscribed nicks over the years and they were all primarily based in Tanx.
Deleting those games is deleting a huge part of this website..and its history. 2001 is when Tanx came out..along with Darts and Billiards, all those years and still people here playing them here and there, think that says something itself.
No harm in bringing a new game but shouldn't delete the old to do so, adapt and expand is the right way to go.
