Yeh it's definitely worth it, hope you manage to grab a copy sometime.No sadly the first one is still full-price too. I put it on wish-list at Deku Deals so I'll know when it gets a sale :)
Have you tried Dragon Ball Fighter Z? Even if you don't like playing fighters online, the single player is a blast and it is only £8 on sale. It's got easy input options too if you prefer, and it looks incredible.
Blasphemous is a pretty good Metroidvania too, on sale.
EDIT: just noticed you updated to say you were some, enjoy your games!
