There's something about the first one that made me like it better. Transformed may have been the more polished and perhaps even technically better game, but I always have kind of preferred the first. I liked its tracks, gameplay and challenges. Maybe part of it was the shock at how it actually turned out well and how much fun I had with it, but it was a damned good game either way.
It did bug out on me and not award credit for 100%-ing it, but oh well. It was difficult to fully complete all of those challenges.
I never did finish Transformed, though not intentionally. I plan to go back.
