I would play master mode more often if it weren’t for the limited saves. It can be a fun challenge and add to the tension of SASO runs and whatnot, but it stops me from playing master mode more often. I’m used to saving anywhere after 30 years of PC gaming, and the family could need me at any moment. I know some people love the limited saving though, and wouldn’t want to take away their fun.
So I was thinking about a subtle tweak that would make it a little more workable as a common mode to play for people like me, but keep the limitation idea in place. My thought? One save per target, or one additional save for 3 targets, either way. This would keep saves limited, and still give you that tension and challenge, but be a little more lenient for people with families and limited time.
