51:17ilia.demianenko Could you expand a bit on "OOP is not ideal for achieving the full artistic vision"? Is it about sacrificing features to hit performance targets, or do you see OOP inherently limiting even for smaller artsy projects?

53:36s0lly Great talk, thanks. Are there any cases where DOD is not a good design philosophy for game programming? Should it only be used for specific sections of game code, e.g. ECS, or should it be used more widely? On that note, is there any specific case where OOP is very useful?

55:33ryanfleury During your training, do you bring up the idea of understanding your constraints as a way to not optimize your data streams more tightly? I see many people start with the assumption of a tightly data-oriented ECS, and their game ends up having ~100 hot, simple entities at any given point in time. Is this something you explore with teaching people how to profile, etc? In other words, DOD thinking in order to accept slop
