ARK:Survival Evolved, is a Survival game of epic proportions.
It can be played on PC, Xbox, or PS3, and has hundreds of servers with thousands of active players.
Its a free to play (one time purchase) and has hundreds of hours of fun in it.
I think this game is a good fit for JSP due to the nature of its game play.
One can acquire goods and materials in game and trade them to another JSP user for FG.
This could be extremely beneficial to ARK players, especially new ones, and could also increase activity on JSP.
A little word of mouth in game, could draw people from ARK to JSP (new users) which is always a good thing for a forum.
This game is extremely fun, and extremely hard, and is in Early Access, due for full launch this summer, I'm told.
It is also on sale on Steam right now for 10$.
Thanks for your consideration and time. ~
