The Choro Q series of games is the biggest mess of mixed up titles I think I've ever seen. The series ran from the mid-90s through the late 2000s, and instead of just calling the series Choro Q across all regions, they perpetually juggled a slew of different names around between the NTSC and PAL regions with each installment. So when one entry in the series would be called Gadget Racers here, in Europe it would be called Penny Racers, then the next game would be titled Road Trip here, but be called Road Trip Adventure there, then the game that was to be released as Road Trip Adventure Avenue here was released as Gadget Racers there. Of course, the series ended on another Penny Racers title, which is what it started as in North America, but was never known as in Japan. Oh, and at least one of the titles actually made it out as simply "Choro Q" stateside. It's the biggest cluster**** ever.
Cool series of games, but I believe the marketing was nothing short of sabotage in the west.
