Dekkar: For the most part, P2 follows the Monty Python adage of "now for something completely different".
While the graphics will remind you of "Prophecy", the gameplay sometimes has an "arcade" feel since, in contrast to the way combat worked in P1 for example, you'll have little choice but to face and defeat all foes in a given area before you can practically jump into a new area. (Origin claims that a player must be "over 2500 clicks away from all opponents" in order to escape combat, but in my experience that does not always hold true.)
Still, if you're a devoted WC fan, how can you not play P2? Tri-System space is part of the WC universe (and IMHO is worth exploring if only for the fun of trying to figure out if there are any "connections" to the inhabitants of Confederation space).
Be warned though, the game does not like fast (Pentium II/III/IV) machines, and so you may have to use special software or otherwise tweak your hardware in order to run it successfully.
