I'd like to add a thumbs-up for Gwenthia. I've helped playtest some stuff with Loz (but I have no commitment or other ties to the project, so am 100% on the level) It's free, it's new with chances to have your own input, it's actively being developed, it's detailed, it's familiar yet unique and mysterious (a cool mix of gritty fantasy with a wee bit of sci fi), and it's now MRQ-based.
As a committed Gloranthaphile/RQ hound (I've played basically no other RPGs except RQ in the last ~20 yrs, after playing pretty much all of them in the 80s), I can vouch for it as a great game world. I'm stubbornly hard to win over, and I'm hooked on it.
