Follow the Leader: The series was obviously Konami's answer to the Sonic the Hedgehog series, complete with high speed action elements and a cute little Mascot with Attitude. The series setting and content is more than distinct enough to keep Sparkster from being a mere ripoff of Sonic, fortunately. Unfortunately, this was the series own undoing, as people often lumped it in with other dime a dozen Sonic ripoffs, which kept the series from becoming anything beyond a sleeper hit in sales.
No Export for You: Rocket Knight is available in Europe... But not on PC. The Steam version is a US exclusive.
What Could Have Been: Not the games, but rather in Sonic the Comic. Fan demand for a new installment of Sparkster stories were high, but Fleetway was Screwed by the Lawyers as they no longer had the lisence to work on a second Sparkster story. Sonic the Comic – Online! has had a Sparkster story on the backburner, but it has yet to materialize. Said story would also work as a crossover with Sonic and NiGHTS into Dreams..., with Reala being the one to incite the crossover by fighting and defeating Sparkster.
