Runequest is an ancient system, pun intended. It's ancient in that it was born in 1978. It's ancient in that it's not medieval, it's bronze age. Instead of 'Tolkienesque Medieval' think 'Harryhausen Clash of the Titans'... yes you might find yourself fighting giant scorpions and the like. Some of you might be familiar with Call of Cthulhu which uses a similar d100 system. We'll be using a trimmed down version of 3rd edition, because it's the edition I am familiar with.
IMPORTANT: JUST OPEN THE CHARACTER SHEET AND GET STARTED. ALL THIS WILL LOOK LIKE AN INFORMATION DUMP, BUT AS IN CALL OF CTHULHU, WHEN YOU FINISH FILLING IN THE SHEET, THE SHEET WILL TELL YOU EVERYTHING YOU NEED TO KNOW TO START. IT'S REALLY VERY INTUITIVE.
