When playing Monster Hunter World their are no event highlights available. My idea is to show the times where you faint and/or when a monster is slain would be useful.

this would be a funny way to fill up my hard drive with uneccary clips

Mark whenever you get an achievement in Minecraft (Java & Bedrock).

If I get a cool kill I was be able to save it

I believe this idea would be simple enough to implement, even though i have no experience in your field, as it would work the same as it would work the same as other highlight systems for enemy kills in your supported FPS games. This would benefit...

I make videos about BF1 on YouTube and I'm trying to make a kill montage. I saw an ad for Outplayed somewhere and thought it was the perfect tool. However, it does not support highlight recording for Battlefield 1.

could show highlights of killing mobs, taming animals, killing mobs, breeding animals, sleeping and maybe more (interacting with objects, or mobs)

It's fun

make it so that it records boss fights

Gw2 is a MMO with the best combat gameplay and mechanics and also the best pvp experience. So why not
