Such sad news.
Sunset Overdrive was a fantastic game, amazing art, decent gameplay with some original mechanics and lots of tongue-in-cheek humor.
Downside was that it was a collect-a-thon, but that is easily forgivable.

It should have released on more platforms to appeal to a larger audience and attract more gamers for the sequel as this is one of the bad sides of exclusivity if it doesn't do well on 1 platform.

Sounds like you would enjoy ratchet and clank ps4. You should get it.
