Grim Fandango (duh!) gets a replay every 6-7 years. I currently am due for a replay but I'm holding out for the remastering that'll be out next year(!)
I replay quite a few other classics every now and then, but nothing quite as ritualistic as my Grim Fandango replay sessions.
I get a lot of pleasure watching my wife (she isn't a "gamer") playing through my old games for the first time. I don't quite get the same joy/scare/feels etc. out of them as I did when I was younger, but it's beautiful to see my wife does.
