Okay I've got two answers one without power on the island and one with power. For the one without power I have to go with Lost in Space...Heather Graham is on the backglass. That and I wouldn't fret over yanking out the playfield and using the cabinet for a boat to get my arse back to civilization...providing Heather Graham isn't actually on the island.
For the island with power I will go with Lord of The Rings. Only because I've owned my TZ so long that I have had the pleasure of Zoning many many times. LOTR's is new to me and seems deep enough to keep me busy for a long time.
