Awesome. I remember an older review stating that this game was built to be a clone of GTA (the original), but the devs loved retro stuff so much they threw in a bunch of other stuff (or maybe it was the other way around). Anyway, it is guaranteed I would enjoy this.
I just thought I would share this vid from the developers that already has 80k in views, but i found it to be an interesting insight in [retro] development. The assets/coding, etc... used for the development were all available in 1989, so the game could have been made then.
btw, this team is insanely good at marketing. Also, the game has already extended to Wii (WiiWare), Xbox 360 (XBLA), PlayStation 3 (PSN) and PlayStation Vita.
