The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
My homebrew for AD&D 2E used this kind of system. Certain actions had action point values that you added to your initiative roll to determine when your next action was along the track. Movement was usually considered to be part of the action if you wanted it - you determined where you were...
