STTNG was our first pin and I'm a big trek fan, so I doubt it will ever leave our collection. I still play it quite a bit and the difficulty is what keeps you coming back. It is deeper than WH20 but WH20 is much more of a crowd pleaser. STTNG is hard for the casual player to get into. WH2O is our most recent acquisition and is really fun. Both look great with a color DMD by the way.
