Quoted from Spock:It is a very fun game, however almost everyone I know who bought a shadow including myself sold it after a year. Granted it was a very fun year playing the game, it just did not last forever. STTNG on the other hand, never gets old and has replay value for "generations".
I'm with you Spock. I currently own both STTNG and The Shadow and love them both, but if push came to shove.....the Shadow would go long before STTNG. STTNG just has a more rewarding feeling when hitting certain shots or certain objectives (i.e. hitting all 4 quadrants during Search the Galaxy mode; ripping a double super spinner; completing multiple Picard maneuvers during warp factor 9 mode; drilling the borg ship via the delta ramp during multiball). Hitting the Vengeance ramps on Shadow for super vengeance is also rewarding but there aren't nearly as many in my opinion. That being said, both are excellent games and to me are both at least 4K+ pins to me.
