I think the idea is, rather than successful horizontal market segmentation (that is, where "D&D" and "AD&D" actually court different customers), it merely took the same singular pool of customers and split them into smaller groups that were speaking similar languages but not the same language.I see what you mean, but I am not sure the trajectory would have been all that different if they had only had one game and not the D&D / AD&D split. The two were largely compatible and you could play the adventure of either. The same is still true for 2e as well
