You yourself even said BC wasn't as big of a deal as you thought it would be not too long ago.
I changed my mind about BC (again, lol). Now I think it's great. Essential, even. It's great to have access to some OG Xbox games (with greatly improved graphics) and almost all 360 games.
I've been enjoying the MCC lately. Playing through the first part of that first campaign is so good in 4K/HDR. Looks great.
