major differences:

Movement is not free as it is in 40k each unit has a movement rate 4" 6" etc and there is no such thing as squad coherency. you are a unit (this is the reason for square bases) your entire unit must be in base contact with each other.

Wheeling is dificult to master as you must get used to measuring in curves.

Lizardmen are along the lines of Necrons pt wise, but if you use lots of skinks more towards IG / Orcs in pts. 2000 pts is your average game.

not hard to learn the system.
