For me, what made Monkey Island great was that it was a pretty quirky comedy. I wanted to see what Guybrush would say next.
Further, it shocks me at how bad the graphics are at some of these games after looking at them again after decades. It occurs to me that what I remember it looking like is a heck of a lot better than what it actually looked like. So I'd rather the game not look like the pixely original. I'd rather have it look like I remember.
