wait a second are we still comparing it to previous fallout games??
Previous Fallout games were turn-based and gave you some measure of error if you forgeted up because there was no limit to the time you needed to take in combat. Fallout 3 and NV's FPS combat was incredibly clunky compared to other FPS.
90% of Fallout 3 made no sense and they reconnect 50% of the stuff from older Fallout games because Bethesda forgeted up.
Bethesda can eat stuff and die for all I care, they forgeted up New Vegas beyond measure.
