I don't play Ironman.
I have 3100+ hours in the game.
Your move, OP.
What I meant, which I shouldn't need to clarify but am going to, is that only 16.8% of people bothered to play the game the way it was intended to be played. You don't get achievements if you don't play Ironman, ergo, Ironman is the way the game is intended to be played. If it wasn't, then you'd get achievements without Ironman mode enabled, for example, StarCraft gives out achievements even if you save and reload in a mission many times.
This is always a choice developers make and the vast majority allow players to earn achievements as long as they play the game without mods, they intend saving and reloading to be allowed. But EUIV is not one of these games, you cannot earn achievements without ironman, so you can only presume that you are not playing the intended way if you are not using it.
Which makes sense. The developers do not want you to save and reload your way out of all the negative events that randomly occur to your nation. They want you to play a balanced game, where some good and some bad things happen to you and you have to manage both, not reload your way out of them.
You already knew this though. You've spent 3100 hours roleplaying and/or sandboxing and I have no particular problem with that. If you are enjoying that then more power to you. But you've not been
playing the game. A game is defined by it's rules, and the game I've been playing has a rule that says that I can't save and reload my game as I please. You are not playing with that rule, so you are not playing the same game I am, but a different game.
If you don't get that, unfortunately, I have no better way to explain it. So we'll just have to disagree.
