In 15 first turns only irregulars and phillelines units are available. The Greek treasury is only 5000 while the Ottomans are far wealthier. Income has slightly increased in Moreas and Greece regions to help the new state survive the first turns as it is already in war with Ottomans. Now it starts in 1821 and it is set in 4 turns per year. In campaign there are some significant changes as well. Important: you do not have to -and you must not- edit user script unless you want to add other mods and combine them with Hellas Mod.
Moreover you can find some useful futures in menu which you should already know from ETF launcher. No more editing user script or manually move files around. A handy, simple but powerful launcher starts the mod game with one click. The 3rd major release of Hellas mod includes some changes in mod's interface and in campaign.
