General Which TBS game has the simplest way to save your progress between turns?

[quietoffensive]

I was playing one TBS game and there was a blackout due to electricity fault. I nearly cry because I didn’t even know if it was saved. But I’ve played one before and it auto-save every turn, there was no stress, you could just continue anytime. That one is the real MVP. Anything that would make me repeat long progress again, I’m out. With all these interruptions that we face here, simple save system is not a luxury, it's a necessity.
