Quick question - I have the G2 simulator that came with my NexSTAR and am looking at upgrading to more aircraft. So I have the choice of buying G2 lite or the less expensive AFP = both look like good simulators, but I am worried about the connections required for AFP - While G2 requires a simple USB connection, it looks like AFP requires a Serial Port - Serial Ports are ancient technology long since replaced by USB - in fact, my new Sony Viao desktop computer does not even have a serial port connection. Does this prevent the use of AFP?
