Recently, I've been playing loads of Mario Golf: World Tour.
Some of the challenges are just plain ridiculous and Sky Island is starting to drive me insane.
Online Multiplayer is loads of fun though. Best bit about the game.
I've also started playing 999. After enjoying Virtue's Last Reward, it was only natural to give this a go.
Backtracking through the game is one hell of a chore though. Really kills the pacing. Glad they changed it for the sequel.
