BRP is a 'universal game engine', so there are two essential products that, to my opinion, Chaosium should produce for this game:
1 - The first one I would love to see would be a scenario book compiling scenarios for different eras/settings. That should feature high quality scenarios and serve as a demonstration of all the different things you can do with this game. Every scenario should be played with a different set of optional rules to change the system and adapt it to each setting/scenario accordingly. There could be a fantasy scenario in there, a sci-fi one, an investigation scenario and maybe something along the lines of ancient Rome. Different flavours. This could also be a good concept for a 'starter set' product for the BRP.
2 - The second one would be a campaign/setting book. I mean a book dedicated to the creation of campaigns/scenarios/games. Like a much extended version of the 'Gamemastering' chapter of the BRP. It would serve as a guide for gamemasters and for editors willing to create their own setting/scenarios for the BRP.
This way, we would have a scenario/settings book dedicated to players and gamemasters and that would be a good introduction to the BRP, and we would have a more creative book dedicated to gamemasters and to people who want to create their own games with the BRP.
