How much cities did you build? How much pop(#) you had in all cities at turn 20, 30, 40 and 50? On small maps if you don't go NC first and don't build the GL it's technically impossible to reach Steel without RAs(it's multiplayer...no time for early RAs i guess) before turn 60. You need a minimum of 25 science/turn for 25 turns in a row. You need 22 pop(if i count some beakers from the palace) to do that starting at turn 30 or so. Maybe on a tiny map though since research go faster.... That's a lot of iron! Automated workers? really?
