Hey there guys,
I've noticed you included a Vector3_PE class which implements IGameCommand and it works as expected (no idea what PE stands for, though). The thing is, I personally find some other basic structs missing and although I've implemented them personally, I feel like it would be a nice thing to have other Vector types (I don't know if you could make them work with a generic number type. I haven't been able to do it myself easily and I can't afford to 'lose' the time to do it) so they work with byte, int16, int32, instead of only with float, so as to minimize as much as possible the network traffic.
Keep up the great work!
