One I didn't necessarily get into late, nor never played, but certainly falls into the category of, "I got on the train, and at the first stop I got off real fast to pick up a snack. When I returned, the train had left me behind and I never caught up again" would be Pokemon. Played first gen when it came out, loved it, and... never played another entry until maybe a few years ago when the Pokemon GO craze inspired me to check the series out again, and then I quickly moved onto something else.
