Nothing silly about it, Punkus. Some kids bond with their Dads over baseball, or philosophy, automotive repair, or watching pro-wrestling. You and your Dad had City of Heroes.
Every time I read something like this, I feel three things. A pleasant warmth, at being once again reassured that City was more than just a simple MMO to so many of our community. A twinge of envy, as I would have loved to been able to bond with my family members over CoH like you and others have. And a deep, bile-filled, sulfurous, smoldering loathing for NCsoft, for destroying the medium through which these special relationships operated.
I don't wanna speak for others, but it'd mean a lot to me personally if you can give him a hug, and let him know that even if he can't bear to be here due to the pain of memories, he and others like him, for whom CoH was not just a game, are in my thoughts.
