For a Kairosoft game, this one is pretty distinct from the rest. I wouldn't go so far as to say it's challenging, but I will say it's the first one I've cracked open a guide for. It constantly keeps you on your toes with new console releases, sudden events both good and bad, and the uncertainty of how your next release will do... it's a game where player choice has a lot of impact on how your run will go! All the console and company names are really charming and nostalgic, too. Of all the Kairosoft games I've played, this one definitely stands out as especially distinctive. Don't let its age put you off: it's a lot of fun!
