Skiing, mine disking, all things essential to make tribes as big as it got were never intended. All accidents. Which is weird to say cuz I bought it at launch when we were all still using targeting lasers and such and it seemed so amazing and fun to play an FPS not in a scaled path but all over the fucking map with jetpacks and what not. But the elevation of the game was something nobody could have even predicted and it was all due to scripts. Literally one of the most amazing games ever happened by accident.
Good luck trying to replicate that. Even the original devs couldn't.
