> I’d be curious to hear how good D can be in that area
Many of the games by ABA Games/Kenta Cho (Torus Trooper being the one I played the most, a long time ago) are all written in D, as is his BulletML library that is used in most of his games.
Best way to go. It's hard to make something great unless you're personally invested imo. Although, Carmack can do about anything he sets his mind to. Love that guy.
