I think I’m still working on the same save-game of A Link To The Past that I got when I was a kid. I just like to wander around in that world too much I guess.
I started playing Shadow Of Mordor when it came out, I think I had even preordered it. Didn’t finish it until recently, when the Shadow Of War hype got me back into the game’s concepts. Didn’t really play it inbetween those two time periods though.
Pokémon White 2 was another one of those. Got it at release, didn’t end up actually beating it until just before Pokémon Sun/Moon came out. The weird thing was, I’d beaten Pokémon X and Pokémon AlphaSapphire in the meantime so it’s not like I wasn’t playing Pokémon games.
You Don’t Know Jack 4: The Ride also took like 5 years to finish. “You can’t finish YDKJ!” you might say. But, this one has an ending. Multiple endings even. You can finish it. I did not realize this until it happened and it blew me and my brother away, since we’d gotten into this rhythm of playing a few rounds of it just at random every once in a while. It’s actually a ton of fun overall, probably the best YDKJ game, and someday I gotta hit it up again once I’ve forgotten the whole thing.
