Both systems have the same spirit as OA/D&D does.
I am not sure about the various C&C game intro modules, but you might take a look at the
Castle Zagyg Yggsburgh book for a campaign base with many adventures and hooks therefor included in it.
For an intro to the LA game the Living the legend (sic.) module is the ticket, as it also expands the LA Essentials rules set even as it provides a demi-campaign base and a number of town, outdoor, and undergriound adventures.
Pardon my focusing on my own work, but because of it I don;t have a lot of time to spend analysing the creative efforts of other designers
again, thanks for many happy years in gaming. and if you are ever in the virginia beach area, let me know, you'll not need to get a hotel.
oh by the way, happy birthday!
Welcome of course.
I plan to spend Thursday evening, the anniversary of the day of my birth, playing games
Cheers,
Gary
