Finally started watching a (long!) video about the UE Gameplay Ability System. I'd tried to get a sense for it from the written docs, but they just don't go into enough detail on how & why you might use it in practice. More like 1 paragraph on each bit & then "go read the Lyra source". Needing to watch a *3h* video has been a blocker on me bothering to dig more before now.

I don't think it's something I'll use on this game, but I can definitely see the utility. Just a lot of moving parts!
