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.
Morrowind. Every once in a while I reinstall it, but I can’t get over the “it looks like an action game but it’s a stats game” thing anymore. And I never liked Oblivion or Skyrim. But when I was a kid, Morrowind was so full of wonder and stuff to discover. I also wasn’t playing with a guide, so discovering stuff like “You can enchant an item to have 1-100 strength, duration permanent. It picks the bonus when you put the item on, and it stays that until you take it off. So put it on and off until you get a big number. Much cheaper than trying to enchant it to +100 straight out” felt more personal.
Unmodified unpatched original Morrowind had this strange bug where a goblin (can’t remember where, but he was in a castle) would sell you 5000 gold for 5000 gold. He would reset every day so you could continue this indefinitely. Then if you killed him you could then loot him for the accumulated gold you had sold him. (Let say you had done this 365 days it would net you 1 825 000 gold)
Well, I’d say Morrowind is still decently playable today, esp. with OpenMW. Sure it shows its age, but I’d ratber play that than e.g. Oblivion.
I might give it a go, I believe it fixes the exploit where you can increase the stock of merchants with restocking ingredients, which makes alchemy a cake walk, no ? I could never resist that
