Quoted from Manbearpig:
To each their own, but I owned a STTNG for 5-6 months and just thought it was ok. Mine was in good shape but my biggest problem was keeping it fully operational! I constantly had issues and had plenty of repair bills from my tech. I recently bought a ST pro and am more than happy with it! To me keeping STTNG running correctly took a ton of the fun factor away! I feel like Sterns ST is SR masterpiece or correction of STTNG. At some point I would like to play a nice working STTNG and hope to understand why lots of people rate it so high.
It's my belief that there's a difference between a challenging pin and a fun pin. Of course it's ideal when a pin is both challenging and a ton of fun to play. As a novice to intermediate skilled player, games like STTNG, Tron and TSPP are not as much fun for me, maybe because of my lower skill level and limited time getting to understand the rules and the machine's layout. However, games like TZ, LOTR, IJ, TAF have the perfect combination of challenge and fun factors for players at any skill level.
