If you are only talking about house play by email rules against a human player, then of course your idea will work. But a lot of people don't play other humans through email. Most only play against the computer. As we all know, the computer player won't voluntarily follow house rules.
I guess we could release two different mod versions. I still want to stick with working on the regular mod version myself. But if anyone wants to tackle modding the pbem version aimed towards house rules, please do.
Of course you're right. House rules can only be agreed between human players.
Maybe the 2 engines cost for the Ta is a good idea to slow the production (even if I don't like it too much, because there is not any historical reason in it, I think). But I think that a change in the stats is something to do carefully. I mean, I'm playing the 44 campaign and I'm in final may 44. All those months I have litterally lost hundred of Bf 109G6 because of the US super fighters (P-47 and P-51). I learnt to fight them trying to minimize my own losses... But I think that the stats maybe are correct (aren't they?). If the allies find the Ta unstopable, maybe they have to adjust their strategy? But I'm not sure if it's fair to reduce the Ta his stats, unless they have been overpowered by the developers.
Probably making this moddel harder to produce and raising repairing times could have a result reducing the Tas production and general availability of planes due to repairs and maintenance.
I think that usually JGs had a good number of planes grounded in maintenance and repair due to lack of supplies (am I correct?).
Is not possible to change the abailability date of the axis planes? If it's possible, it could be a possibility to add some months to the historic (?) date. That will force the axis side to waste resources in research only to receive the planes in the historic data, and a "real effort" in research and lost production in order to advanve that date in late war wonderweapons.
Just some thinking about it... I hope that it will helps.
I can't say anything about the allied side, because i have not a lot of experience in this game and i know better the luftwaffe side.
