>>714321014 (OP)Do you mean "in the way a child does"? I still get that feeling when I play couch co-op/vs games, every Christmas my friends and I (all adults) rent a cabin in the woods for a few days to hike and chill and at night we usually play board games and old video games like Street Fighter 2 turbo and Streets of Rage 2 and we have a blast, gives me those old feelings.
For single player stuff, I finally got around to beating Fallout 1 recently and loved it, and have been enjoying some arcade racers like Burnout 3 and Flatout Ultimate Carnage, these all put a smile on my face.
