Savage worlds kinda defeats the rifts idea, if not the setting. The whole point of Rifts is you can have kung fu immortals next to Atlantean tattooed undead slayers and young dragons with gigantic robots in the next frame... I have run 3 different awesome Rifts campaigns - One a gloriously hopeful "Hotbed of Humanity" - Seven Human Samurai fightoff evil magic raced bandits, "Mechamecha High Mechaheiney Ho!!" where players were all in giant robots of different settings and trying to just do maximum damage each , and a "Phase Off" series that was sorta a gritty detective series on phase world. I had two ideas I'd kinda want to turn - one, a sorta cowboy western low powered setting (regular Rifts) and one a higher powered mecha setting (Coalition v2 - vs Splugorth invasion)
