We're lucky they didn't stop at 30 - st3lt3k reports that Wing Commander IV (just) made PC Advisor's list of the The 32 Best PC Games Revealed. They say it better than I can:
Genocide. Treachery. Friendship. Defection. Galactic heroism. Wing Commander IV was the last game of the series to be helmed by creator Chris Roberts, and it was, by far, the best. An interactive movie and space flight simulator, it had us playing as a mature and seasoned Mark Hamill, ducking in and out of the cockpit and exploring a vast web of branching storylines. Surprisingly decent acting, awesome gameplay, and a story that belonged in theaters made The Price of Freedom one of the sweetest games of the 90s.
