Is it possible to mod Marius Reforms?

Is it possible to mod Marius Reforms so it no longer takes place only after 220 BC at 1.2v? How do you do that?

No, the marius reforms are hardcoded.

The Marius event can be modded to some extent (this is for RTW 1.2 only, there is nothing much to mod in other versions). You can change the earliest possible date for the reforms by changing the start date of the campaign, and adding a campaign script that jumps the date backwards or forwards. For example, if you want the reforms to be possible right from the first turn then you can set the start date back 50 years, and then use "console_command date" to jump the date forward fifty years when the campaign starts. The campaign will still appear to start in 270 BC, but the turn counter will be advanced enough to trigger the reforms.

Thank you very much Dime, thats a very good idea.

Oh, I forgot to add one detail. Jumping the date will also trigger all the historical events in the period jumped over. To avoid that you need to delete them, or adjust the dates that they occur on.
