For those of you old enough to play GTA 1 and GTA 2, how popular was the series then before GTA 3?

[S.T.A.G.E.]

Gaming sales during the N64, PS1 one was about as healthy as it could get. GT had great sales in an era where no other racing games in its league outside of the fun kiddy games. It was wildly popular alongside Crash Bandicoot and plenty of other games.
