INTRODUCTION & GAME STATUS
Here we are, the last comparison of FRGCB. Well, at least, the last one I'm writing. It might not be exactly the most epic possible finale, but I thought it's a perfect reminder of how much more interesting and imaginative top-shelf game developing was at best during the 1980's, than it came to be decades later. Also, considering the number of versions listed above, it's bound to be a properly big one to end with, featuring most of the regular "contestants" and then some. In case you didn't arrive on this page through one of the forum links I have infested with my spam, click on to read, and hopefully learn something in the process.
