I thought it was interesting that the linked article said it became reminiscent of Doom 3 in terms of the darkness and horror, but I think Doom 3 was chasing that same darkness from the original that somehow became less dark over the years with the emergence of better display technology.
> Crispy Doom is a friendly fork of Chocolate Doom that provides a higher display resolution, removes the static limits of the Doom engine and offers further optional visual, tactical and physical enhancements while remaining entirely config file, savegame, netplay and demo compatible with the original
Most purists will be fine with Crispy. It doesn't require a PC more powerful than a 2001 one if not less. Pentium MMX-2, if any. Or ARMv5. Because of SDL.
(G)ZDoom is another level.
It also seems like you are missing GP's point. "Better" is a loaded word because it implies a quality by which to measure, but Chocolate is better than Crispy for the exact purpose GP suggests it; it's more accurate in terms of the presentation and limitations of the original. Chocolate looks, sounds and plays like the original, with few compromises.
