I think that the set up of forts and settlements in the West is set up for 1755 or 1758 rather than 1775. I see a lot of forts and towns that did not exist at the time of the Revolution.
In particular:
-Fort Toronto/Rouille (Anglo keyboard no egout

-Kingston/Fort Frontenac. The British took Fort Frontenac in 1759 and destroyed it. The area was abandoned, and there was no European settlement until 1784 when the loyalists arrived.
-Fort Venango was destroyed by the Indians during Pontiac's revolt. It was never rebuilt, and as far as I know there was no (European) settlement north of Pittsburgh at the time of the revolution.
-Fort Miamis. I'm not sure what this represents, but I'm pretty sure there was no fort in this region during the revolution (which is a reason why the Americans never made a real attempt on Detroit - no staging areas). The forts that I know of in the region are
Fort Miami (at the mouth of the Maumee river)- built by the British in the run up to the Fallen Timbers war. The battle was fought right nearby. Anyway it was built after the peace of Paris and was handed over to the USA under Jay's treaty in 1795
Fort Meigs - built by the USA in 1813
Fort Sandusky - built by the British in 1761, destroyed by the Indians in 1763.
Fort Miami - modern Fort Wayne IN, destroyed by the Indians in 1763
The lesson the British learned from Pontiac's war was the small forts with small garrisons were very vulnerable. They changed their policy to holding a small number of strategic forts with more force. Most of the forts that the French had built to contain the British settlers were abandoned.
