Here you can see how India beats Iro FF, even after insane age 1 for Iro.
Step 1: Rush, do the damage. Shoot vills, deny crates, kill hero, idle him.
Step 2: He ages up. Go back to side, get your eco up and prepare to age up.
Step 3: Now it's going to be FP in your base. You barely started aging. What to do? Make a counter attack with leftovers sepoys, kill more vills and force him move back.
Step 4: Now you reached Fortress. Here, continue harass with raids sepoys, ship urumis. Once opponent is distracted with your sepoy raid, pop urumis and half of your army to his face and clean or damage his main army permanently.
Step 5: If he is not resigned yet, you will simply outeco and outmass. Spam more sepoys, use cease fire, go industrial, the world is yours.
One of the best india games where I stay in control all game despite being much slower civ.
