Games come and go. Just like what happened with quake, quakeworld, doom, quake team fortress, half-life death match, diablo, diablo II, asheron’s call, everquest, daggerfall,,,, and hundreds of other games.
Remember the good ole days of playing the games you enjoy. One day you will tell your kids of the good times you had.
I still tell my kids about what quake was like in 1997 and 1998. When we used to play diablo II I would tell them stories of what it was like playing the original diablo on dialup.
As for myself, my kids and I used to play l4d / l4d2. Now my grandkids and I play.
