* Tribes 1 revolutioned the FPS scene by allowing fights on big landscapes, and by using vehicles together with "soldiers"
* It had, and still has, one of the best netcodes which allowed even 56k people to be a real threat
* Extremely hard learning curve - sadly, this is also the reason for it's death (not a single insta-hit weapon in the game, all the weapons need leading, and most of them have rather slow projectiles)
* Adding the Z-axis into a game by giving every soldier a Jetpack
* Additional to the Jetpack was the "skiing", which means to move you had to use the terrain arround you and slide down hills (which even made movement a skill, which not just included holding the "W" button, but seriously took a lot of practice untill you got speeds right)
* You were moving around with speeds up to 300 kph (with or without vehicles)
* An itchy trigger finger and milisecond-reactions were not as important as experience and a lot of thinking-ahead
* It's a teamplay game which needs lots of tactics and communication
* I was so addicted to it (too bad it's dead now, hardly anyone playing any more... )
