It's probably needed to ignore actual years. Can't really have ruleset changes making the game to actually run the real years so maybe better to ignore this.
The start techs? Probably WW1 level techs are needed but what are thos exactly?
How expensive should it be to research new techs and should there be a "barrier" to prevent the players (easily) from researching too advanced stuff like nukes and stealth units. The techs could be made more expensive by changing the actual costs for each of them. This is not really too much work if we only know where to start from. What would be the first techs that should be "too expensive"?
Also, is there need to adjust some specific WW1 techs or create some WW1 specific buildings? How to deal with unhappiness?
How to give the players more reasons to keep units on the front for simulating the stationary war? Or is there a reason to do that at all?
Probably some later units need to be available before they would be in a regular Freeciv game. Like Tanks and maybe howitzers? How to change the actual values for those units?
And the map. Should the game be once again with 2x moves? How did the 2x moves work in SG1?
Anything else? Please don't hesitate mentioning or listing stuff. Rants are also welcome
