If you never played the original then picking this up is a no-brainer. 3D World is a fantastic Mario adventure, and you shouldn't miss it. However, if you already played the original on the Wii U, Bowser's Fury and the added online play don't quite make it worth the full $60. That being said, it's absolutely worth it if the price drops even a little, or if you just really want to play 3D World without having to hook up the Wii U. It's a great game, but it still feels like Nintendo should have done more with it.
Little Nightmares II is just a worse game than the original. Everything they added to the system feels clunky at best and unfair at worst. It's a shame because this same story, with its same environments, same levels, same enemies, and same music and sound would have been infinitely better if they kept the mechanics from the original.
Hitman 3 was a fun game, but I definitely put it down quicker than I did Hitman 1 or 2. If you wanted more of the same it gives you that on top of being a really convenient platform for the content of the previous games, but that doesn't change the fact that this feels much more like an expansion pack than a new entry in the franchise.
I want to recognize how ambitious and fun this game is while simultaneously warning people about how incomplete and sloppy it is. Whether or not this is a worthwhile purchase will be entirely up to whether or not you want to brave the bugs, glitches, and general half-baked feel in order to get to the core roleplaying game underneath.
