I just stumbled upon Paige Oliver's Red Box Fantasy rpg (Player's guide here for free), a game that is described as "the new face of Retrogaming." A more in depth description can be found here.
Jim Raggi is kicking around the idea of a LotFP traditional rpg in order to market his games under his own brand.
With S&W, LL, OSRIC, BFRPG, M&M, etc., as well as similar themed companions from Barrataria and Blackrazor, do you think this fragments or waters down the OSR, or do you find more options to be healthy for gaming references/growth.
I mentioned before that I think that most old-school gamers love to draw ideas from various sources. As a young roleplayer, I used to mix B/X with a fat dose of 1e and a dash of the ol' Arduin Grimoire. That being said, I am all for more ideas based on the old game we know and love to be written and available for public consumption. For I shall consume, see?
I would like to believe that someone who mainly plays Labyrinth Lord or BFRPG would have no problem utilizing other retro-sources into their game if they wish. If not, for those who use a set of their choice rules as a strict source for play, why would/should it bother them that other retro rules exist?
To ask if more and more retro-clones are necessary is moot. That opinion is up to the one who might want to use additional rule sets for inspiration. For those playing strict B/X D&D by the book (and with the originals no less), of course new sets of retro rules are unnecessary...for them.
For me, I like a variety of ideas on my favorite game, whether it comes from the 0e or the 1e spectrum of play. So I read through and utilize bits from most of the clones, as well as the supplements and magazines. If Raggi publishes the LotFP rpg, I'll read it and possibly use it for inspiration in my LL campaign. What I won't do is roll my eyes and say, "ANOTHER one?!" The quality and love put into the available clones (as well as the wealth of ideas) are seriously not that off-putting. :)
