Well...in a way there are no vehicles in the game at all...
All current "vehicles" are really morphs ( changed player forms )...
Which is part of the problem of adding seats, changing color etc...
You ARE the vehicle. And I'm not a 2 seater
Which is also why you dont have vehicles you can visible sit, stand etc on...
Having actual vehicles that are not player morphs would be very very nice...but would require quite a lot of new code in the engine, I suspect.
Not only for the possibility of changing the look, but could open up for crewed vehicles with gun turrets etc.
Even riding animals would be nice. Or pets as Mürten suggested.
Have you seen the plainscales in Mort ? They have a rider on their backs
Imagine being able to charm a large animal and ride it...
Or a Leet for that matter... hehe
