About REXing:
Build many Settler ASAP (On Emperor I first grow to happy cap while building Archers) and block land to backfill. The new cities should start building a Monument first (if not creative). Work a 2F tile (if no 3F tile is available) and whip the Monument as soon as you reach size 2.
You don't need to wait till the Industrial era for an attack: Read one of Acidsatyrs games, he is one of those players who needs about 10 turns to build conjure up an army, leaving crippled cities behind but that new army instantly gained a few more cities. Meaning you can beeline Maces and attack with them if you like, you also can swordrush. Just watch your expenses carefully, F2 is your friend there.
Keep in mind that on Monarch, any game can be won without a single war. The more you REX, the less you need to be warring. Score doesn't matter. You can minimize that list by clicking on your name (I recommend that). It has a slight influence thought: If you're the scoreleader, the AI demands less tributes from you and give in more easily than if you're last. But it doesn't reflect the current situation.
