Look what I found: a ten year old upload-picture to Digitalpress.
Back then I asked about games of the Gadget Racer series which I found very interesting to play and collect. I got them all for the PS2 and GC and still haven't played them.
Thanks so much for reminding me of ChoroQ! I remembered that I thought years ago of playing the game for the reasons you listed. I completely forgot about it. A car RPG by Atlus, that sounds interesting. ChoroQ is a candidate for sure for the borderline category, maybe even for the main list, let's see. Have you played them? What's your impression?
This is a great opportunity to try the games out. I will also look into Roadtrip, which got a release for the Gamecube as well. Both games are still sitting sealed on my shelves, silly me.
