Yeah, the PRTO entries don't like empty spaces.
*Sigh* One day™ I'll make a scenario for Iran and/or India, those æternally fascinating civilisations.You might consider making their golden age triggers buildable with that government. Also, most mods choose to focus on Northern India. It's worth taking a look at the Dravidian culture(s) of Southern India for your mod. Roman luxury imports from Central/Southern India via Africa were lucrative enough that the Roman Senate had debates about balance of trade, to give you an idea of their influence.
I'd recommend taking the Chola dynasty - which spanned from the Classical era up through the 14th century - as your model. Their cultural accomplishments are often referred to as the Indian Renaissance.
I'm pretty sure that Rob made some appropriate leaderheads. There are certainly enough units.
They had an impressive navy for the era. Not as landlocked as the Northern dynasties. It's the era when Indian culture really spread into the Malaysian peninsula. Places like Angkor Wat were built by Indianized states.
