Maybe the definitive version of all of these games? That's up for debate certainly, but there is more then just the standard graphical improvements here; these are full blown overhauls, maybe some of the earliest Nintendo did, and the QOL changes that they do make all of the difference. Super Mario Bros. 1 in particular feels like a completely new experience while retaining that game's unique individual quirks, which is not an easy feat.
There isn't a whole lot I can say about this that hasn't already been said in my other write ups for these games - all stills classics across the board - but honestly if you are going to play 2D Mario this might be your best introduction. A clear, unfiltered view of how timeless these particular installments are while giving you a better experience then the originals. One of my personal favourite compilation titles, well worth getting.
