Haha, I haven't been here in a while. Still haven't gotten much done with part 3. Changed some stuff, but still not finished.
I've got some ideas for a 4th and 5th story as well. The 4th follows the same storyline a few years down the road, while the 5th is a spinoff focusing on a different group of people. Both take place at the same time(kind of like Initial D 2nd Stage and Extra Stage), and actually cross over a bit.
I came up with some interesting possible villains, something possibly even worse than posers and ricers.
