That said, one of the killer features of the tactical fps game Valorant is the sound you hear when defeating another player. It’s incredibly pleasant and satisfying in a way I haven’t experienced before, to where it feels a bit like a psychological conditioning reward. Despite being a somewhat similar noise, the effect is the polar opposite of the Windows string hit.

If done in quick succession it builds to a little sting at the fifth kill and if that wins the round, an announcer declares “ACE!” in a way that players clearly find extremely gratifying.

I’m not sure how to pull this off in an app. People have certainly tried, but, as an example, the ‘woosh’ noise when sending an email in Outlook isn’t something I look forward to.

However, I think I’d file this under ‘great UX inspires great UX,’ as there are plenty of games with bad or frustrating UX.

Also, is it a common thing now to call any complex branching hierarchy ‘fractal’?
