Flashback Nation, a Twitter account dedicated to all things retro, recently put up this scanned cover page of the Winter '94 issue of 3DO Magazine UK. Wing Commander 3 is featured prominently on the cover, and the issue included a review of the "$6 Million Dollar Game." The coverdisk (which appears to be free sampler disk #1) would not have included the playable 3DO demo of Wing 3. That was included on the third interactive sampler disk, published the following year.
I remember this issue of 3DO Magazine, Bought Wing Commander with the console because of this. No regrets.
