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.
This is not BOTW2, but it's still a very fun game that is worth your time. It's fanfiction with an awesome hybrid action-RPG with BOTW mechanics attached. Just don't get too wrapped up in the non-canon Ganon and you'll be fine.
If you are a die-hard Kingdom Hearts fan that loves the music and needs to play every game, then yeah, this game is for you. However, it just feels sloppy for a full-priced game. There are better rhythm games out there, and better Kingdom Hearts games out there, so unless you really need a combination of the two, you can safely pass this one up.
Miles Morales' biggest problem is by far its length which will turn some people off. But honestly, there's room for more short form experiences, even as major console release titles. Miles Morales doesn't waste any time with padding and instead keeps pushing high quality Spider-Man gameplay at you, which in my opinion is a strength, and not a weakness.
Yakuza: Like a Dragon is worth your time. While you might not like it if you were a fan of the older Yakuza titles, or if you are looking for something dark and serious, anyone who just wants to explore Japan while having some fun and beating some gangster's faces in old school JRPG style will love this title.
Fuser is a great little program that serves as an introduction to the art of DJing. It's just not much of a game. So think about this as purchasing entry-level DJ software, and as entry-level DJ software, it's pretty good. It's never going to be as powerful as dedicated DJ software, but if you just want to have a bit of a DJ fantasy then Fuser will give you just that.
Watch Dogs: Legion is an interesting game with an innovative system and a compelling story. It's not a blockbuster hit and it probably won't make the running for GOTY this year, but its experimental systems and socially resonant plot make it worth checking out.
