I would answer that question with an unequivocal YES for two very important reasons:
- LL is an established brand with a license that hobbyists like myself and small publishers can easily and legally publish under with full knowledge that whatever we produce can be used by those who want to do the B/X thing with virtually no conversion at all.
- More importantly to me, LL has a library of compatible games that are specifically designed to be modular. Original Edition Characters, Advanced Edition Companion, Mutant Future, Realms of Crawling Chaos and Starships and Spacemen 2e are all specifically designed to be able to be integrated together to create all kinds of cool homebrew campaign worlds without having to house rule. In addition, Dan Proctor has provided several free .txt documents for us hobbyists to do exactly that.
Despite the fact that I gleefully grabbed up the .pdfs of B/X (and was very pleased to see how well they are bookmarked) I still plan to use LL as my default ruleset precisely because of the versatility it provides me as a hobbyist. There are still many things within the LL library that await to be exploited to go places where B/X on its own can’t go without a lot of work that has already been covered by the LL library.
Thus, while I am very happy about what WotC is doing for the hobby and they deserve my gratitude and thanks, Dan Proctor also needs to be thanked because his work has greatly expanded the awesomeness of B/X and taken it to places it never went on its own.
