Quoted from markmon:Agree. But to answer the question, I think sttng has more staying power. There's a lot more to do.
WH2O is a fun game, but STTNG has more going on. I had a WH2O and sold it, STTNG is still here and always will be. I am not a huge Star Trek fan, but I appreciate a really well made, deep, challenging game and there isn't anything better than STTNG.
