IMHO opinion NOBODY wants complete historical accuracy in wargames - we all want our own interpretation of accuracy. Does the tactical squad leader player want to take his iPad into the garden and physically crawl through the dirt in a rainstorm while he ponders how to assault the next pillbox on his screen? I'd say he'd rather sit on a chair with snacks close at hand (and I don't mean K-Rations). I know there are ACW re-enactors who starve themselves to get into the gaunt Confederate soldier mindset but I doubt anyone does that just to play Forge of Freedom.
OK, that's just one tactile level of "accuracy" and not relevant to operational/strategic games but it is these larger scale games when the problem gets worse. There was an interesting discussion in the "Time of Fury" forum about whether a successful SeaLion should be achievable within the game system. One group of purists held that hindsight showed that the Germans would never have succeeded in invading Britain and the game should reflect that reality. The other group of purists (including me) acknowledged that SeaLion would have failed in real life but at the time the British were operating under the belief that it MIGHT have succeeded and their strategic decisions were affected by that belief. If you removed the possibility of a successful SeaLion from the game system then you were not accurately modelling the challenges facing the British ("Hey, since we know the Germans can't invade the Homeland then lets just send the whole RAF to Egypt and wallop the Italians."). And why would the Germans divert part of their 1940 production into transports (as they did historically) if they know that those units will never be used in anger? So which 'accuracy' do you choose? Operational planning or strategic mindset? You can't have both in that situation. D@mned if you do and d@mned if you don't - the game designer just can't win.
I agree with DSWargamers point about allowing variable setups (and starting forces) in order to defeat perfect plans and perhaps that's as close to "accuracy" as we can hope for. OTOH he also said "You are kidding yourself if you think most computer wargames are giving you 'great' wargaming." and with that comment he perhaps risks portraying himself as the sole arbiter of what defines 'great' wargaming (I'm sure that wasn't his intention.)
"Great Wargaming" is different things to different people and for me... Pandora=[>:] + MWiF=


However I do exclude weapon performance from this thesis. While an Avro Lancaster will always carry more bomb weight than a Mosquito there may well be a viable discussion about whether the RAF should have scrapped all of the heavies and just built swarms of Mosquitos... you'd have to miss out on events like Operation Chastise but the overall effect may have been well worth the sacrifice.
So (reaching for tin hat and hunkering down under my desk in anticipation of incoming fire) what do you think?
