Y'know, subject-matter aside...
Pilotwings 64 isn't/wasn't a million miles away from what GTA became ... obviously it wasn't anywhere near as free-roaming, and all vehicles were aero-naughtically (is that a word?) themed, but I can still see some correlation between the titles...
The different vehicles and set tasks etc...
Perhaps Ninty could incorporate some GTA sandbox elements in the next PilotWings game (on Wii)
