Well, it seems like Final Lap Twin is definitely preferred, I also just noticed that it is 2-player splitscreen! Oh wow, I had no idea it had quazi RPG elements. Heheh, this one is really awesome.
Is Victory Run anything like Rad Racer or Outrun? It looks like Victory Run has different backgrounds, but that doesn't scream branching path cross country driving clone to me.
Hmm, has anybody noticed which racer has the best animated sprite scaling (think tech demo)? The PCE's speed from ROM would probably mean that there would need to be a larger HuCard for any racer to show more animated scaling. I suppose there isn't a good Super CD-ROM 2 or above racer for the system?
