Recommendations for lower priced PS4 games?

I'm currently off sick from work and have nothing but free time. I was thinking about buying a lower priced game, sort of below £30 (which is equivalent to about $45) that'll just keep me occupied for a bit. I'm not keen on Inside/Limbo-esque games and also don't like, I hate the word but it's the best way to describe it, 'walking simulators'. I know it sounds derogatory but people know what you mean. So if you have any recommendations for a neat little game, including any that are in the sale (£30 is my limit right now is all) I'd be really grateful
