Q: This System is in no way close to how Electricity works IRL! This is stupid!
A: It is not supposed to be like IRL Electricity, it is supposed to be Gameplay based rather than realistic. It needs a simple to understand System, and if I would go realistic like the old UE, then people will probably never understand why their Stuff burns. I do know how Electricity works, but not many regular people do know that (or would ever understand that). GT has Voltage, Packets and Loss/Packet/Meter.
