Well i never played the weg version but i have read the rules and watched several friends play it for about 6 hours.To be honest i never did like it something about it put me off and i'm not sure what it was.
As the orginal book and the RCR book i've played numerous session with them and i found the rcr book the best for me.I've managed to take some of the rules from the original book and added them to the rcr.
As for saga i've only read some reviews and and read some posts from other forums about the game.The game seems good but much like weg version something about it is putting me off.
I've been thinking off taking some rules from the palladuim game system and putting them in my rcr games but i haven't decided which rules i will use or not.
I've also been thinking of adding 2 new ability scores to my rcr game
they are accuracy ranged and accuracy melee. This would mean the strength score would no longer affect how good you hit with melee and unarmed attacks and ranged attacks would not be affected by dex anymore.But i'm not sure if i'm going to add it or not.
