SUMMARY
Titan Quest (2007 RPG) is considered to be one of the better non-Diablo I/II action/RPG clones, in part because it's still robust fanbase and user-made modifications. Anyone who plays Titan Quest regularly should be familiar with Titanquest.net, the premier Titan Quest website and community board...
...Until around May 2016, when it suddenly went off-line and has stayed off-line ever since. Concerned TQ fans have since turned the Grim Dawn message board (Grim Dawn being a game designed by many of the same people who designed Titan Quest) into their temporary refugee camp (no offense to actual refugees who, let's be fair, need as much of our sympathy as possible because their plight in life is very, very real). For a while, there was genuine despair but, fortunately there is hope. TQ.net was originally started by one person, who thensold the site to another person who then sold the site to an entity known as "iEntry." For whatever reason, iEntry decided that it no longer wanted to be in the 'Hosting Fan Website for an Aging Action/RPG" business and promptly shut it down not too long ago before discovering, to it's dismay, that a lot of people still used the site. Therefore, it looks as though they may transfer all of the data from the site to someone else so that they can continue to host the site elsewhere.
Whew.
So, if you need your TQ fix, go on over to the link down below and check out the latest developments on when the new TQ fansite will be up. As is, there are already a bunch of files and mods "recovered" from the old site via TQ fans pooling their resources that you can download from the link. Enjoy.
