Mario Golf: World Tour is a mixed bag. On one hand, it is an almost perfect golf game with interesting and compelling online options. On the other, it adds in a bunch of gimmicks and lacks enough actual golf courses. Still, my complaints are more related to the lack of content that I was expecting, not the quality of the gameplay, which is pitch perfect.
Not only is Salt and Sanctuary a fantastic distillation of the Dark Souls formula to 2D, it is also one of the best Metroidvania games I've ever played. Either one of those would make the game an easy recommendation but both turns it into a must play.
In my 26 hours of playtime, I finished the main story, saw a bunch of optional conversations, and completed 45% of the side quests. It’s fun in a mindless sort of way and it isn’t terrible but you’re not missing anything by skipping it.
