I know this may sound stupid, but maybe LA should make their own engine, here is my idea for the engine:
in the confederacy war room their was a map, on the map their were the republic troops and fighters each unit was a certain size and it looked pretty cool. How bout add color and buildings and recources and you might have a good engine. It gets the size of units quite well because if you notice in Ep.2 the artillary TOWERED over the AT-ETs ( they were at least a lot bigger) and also I was very dissapointed on how the decimator was as tall as a regular trooper?! What the heck is that!?
( I apologise for spelling and punctiation marks, does the pharagraph still makes sense?)
Always borrow money from a pesimist he won't excpect you to pay it back.
