...need to see how sales are going.
An unscientific gauge of this, on Ebay sales showed as REN getting 8 buys to Chancellorsville's 2 during the same period of time from one reseller.
Based on the period and that (afaik) in this format, it is unique for its subject, word of mouth, and AARs are going to play a big part.
I read your Napoleonic pages on tactics, Sgt R - and they were pretty good (excellent, to be honest), and REN could well deserve a similar treatment (no mistake, I am not volunteering anyone for anything... but rather talking about the learning curve involved).
REN can be very formation specific, in that your arq units have to support your pike units and your pike units have to support your arq units, screen off your artillery, you have to cover your baggage trains, and all the while manage some different varieties of cavalry while getting into position to use your heavy cavalry - all the while juggling point gains and losses of which there are many combinations...
Now there is not really a set of tactics for the game, as it is more dictated by the scenario and the forces - in that if you take a scenario like Knockdoe, there is a different set of forces to, say Encounter 1...
Mind you the Encounter scenarios can be a blast -I think Encounter 1 is something along the lines of a massed French Cavalry raid that resuses the Calais map. There is a lot of room for maneuver and a lot of options...
The campaigns also look pretty good, was playing through the Fornova one last night ... the initial scenario is short and sweet at 6 turns, and sets up a larger scenario and choice on the same map for scenario 2.
