In short, The G2 Lite is litteraly the stripped down version. Its kinda like the tale of two Camero's. The two car's look the same but one has the V6,bench seat, auto trans, AM radio and heater only. The other has V8, buckets, 5 speed, AM-FM-CD radio and heater with air conditioning.
They both work and both do a good job! The 2ND just had MORE of everything. Planes, airports and most of all--additional graphics and controls so that you can change most everything you can think of on it. Also LOTS more add ons! Check KNIFEDGE.

My $ .02 worth!
