The combat, inventory, character statistics and dialogue sections have all been tweaked and streamlined, and a whole bunch of cool, new options have been included. The characters get Experience Points from interacting with the world, and those XP are transferred into upgrades for their character in the form of better Skills, Perks, etc. It is the same system that was used in Fallout 1 and Fallout 2. The CTBA lets players move around at any time, but actions like firing a gun cost their character Action Points.
Action Points regenerate over time.
No more waiting for 20 rats to each take their turn. We're doing both Turn-Based and Continuous Turn Based. Two different modes of play. You'll choose to play one or the other. The CTBA works at the same regeneration speed for all character types.
