is it really worth buying any of the 2 and is there a difference with the Dragon Cam? What's the significant difference btwn Diablo 2 and Diablo 2.3. I know the 2 is the newer version but would of thought the sequence of the latest (or better one) goes up numerically i.e 2.4 just like u have in cars 1litre engine 2litre etc. please bear with me I am a freshman on campus
