I’ve been looking at the multi-game guide books that were popular in the mid-90s. This one has chapters on Wing Commander III and IV... but the very simple walkthrough only covers seven missions of the latter. These seem kind of silly today, but before the internet books like these were a neat way to find out about the games available for your system. They’re as much wishbook as they are hint book!
Prima updated this huge book of PlayStation game guides annually for years. Here’s WC3 and 4 still included the 2000 version!
