The newer XCOM games actively remember and give you the same result if you reload. To discourage save scumming. I would get stuck in one where I'd miss a 90%, reload, and still miss. Because the next shot was always going to miss. So I'd take a different shot with someone else that wouldn't matter, come back, and suddenly I'd make that 90%.

The original 90's games, you could just save scum. But you'd still miss that 90 sometimes.
