No, unfortunately there is not enough time available when you grow up and get kids, work etc.
But, there are a lot of good games i am sure i havent played. Not the classics (wings, lemmings etc) but still recall some games which did get good scores in magazines which i haven't tried because i couldn't afford them when i was young (the first one that pops my mind is Perfect General, and also storm across Europe but methinks that was c64?). Good games then, are still good games now? Me thinks so! (Battle Isle still good, Wings still good, Kick Off 2 still good, etc etc)
