"At the same time, the level of hype about ECS today reminds me an awful lot of the amount of hype surrounding OOP in the 90s." I try not to focus too much on the ECS side. It is all about understand the problem you need to solve. If you are making a game, and you know exactly what the game needs to do from a programming perspective... write it. Yes, while I would keep the "data oriented" viewpoint... but do you really need to spent time on some ECS layer? If you know exactly what each character in the game does, write it and solve it. Are you making a game... or trying to create the next Unreal Engine?
