Seta was not a big company whatsoever when it came to publishing, and they only released 3 games for the American public:
Adventures of Tom Sawyer
Castle Of Dragon
Formula One: Built To Win
Notables: Like racing sims like Gran Turismo? then F-1: Built to Win is your game. It is easily the most deep racing title on the NES and I love building up my cars in it. Not only that, it has an in-game casino to addictively gamble for more money to tune your car. You can also save your progress to the battery-backed cart. Adventures in Tom Sawyer is a so-so platformer, I guess I was supposed to learn something about the book from it but I can't say that I did. Castle of Dragon is decent fun, pick it up if you need something new to play.
Status: Pulled out from the U.S. market during the SNES days as far as I can tell. Still operating in Japan but most of their recent PlayStation 2 and Nintendo 64 titles appear to be Mah-Johngg related.
Best Titles: F-1: Built to Win is a MUST buy. No excuses.
Popularity of Games: Below average
Rarity of Games: Above average
Overall Rating: B
