That is completely different.
This is more:
In game X, you can drive tanks. You blow up bike shops. Blown up bike shops turn into military bases and are checkpoints. You respawn as a tank.
In game X2 you can ride bikes, but only on a specific path. But you drive tanks the rest of the time, and blow up bike shops.
In game X3, you start off on a bike, but soon you get a tank. As a tank, you blow up bike shops and they become military bases and serve as checkpoints. When your tank blows up, you respawn with a bike, then ride into the military base and get a tank.
You're not doing anything new in X3.
