Call of duty (in general. Minus the last 3 games since they're awful)
Minecraft
GTA series (5 in particular)
Castleminer z (indie game Xbox 360)
Halo
Pokémon(the mobile versions(game boy/3ds etc.) not the console versions where it's like a battle arena style)
Theirs sooo many games that we play growing up!
Medal of Honor: Rising sun was the goat game when I was young. But overall I'd say minecraft since it's ever expanding/evolving. Endless entertainment and such a grand experience solo or with friends!
