The first game that comes to mind for me is Civilizations 4. I’ve probably spent hundreds of hours playing but after getting used to 5 and 6 I have a really hard time going back. Going back and forth between 5 and 6 I need to rethink some strategies but with 4 I feel like I need to rethink everything. I don’t know if it’s because of the tech tree layout in combination with the civics system, things like unit stacking, or maybe just a bunch of little things but it takes me a while to readjust.
Gen 1 pokemon. It was awesome to experience, but the formula is just better in later versions.
GoldenEye, I did try it years ago, but going back to one stick for a shooter is really awkward.
Wow, I don’t have the time for an MMO anymore and they are a lot less fun after your first experience.
Oblivion and Morrowind, the changes in Skyrim are almost all improvements, and the mod support is better. You can smoothe out the edges of the older games, but it’s a long process I’m not interested in. I’ll stick with find memories.
Have you tried the mouse and keyboard mod for GoldenEye? I imagine it makes everything incredibly easy but it could be different enough to justify a playing one more time
