The ultimate noob challenge

The rules are as follows:

In this imaginative scenario, you, the noob player, are faced off against 5 top players in a 1v5. You start in imperial age with very high resources (but no techs researched yet) while the opponents start with normal resources in dark age. The catch is that there is a 20-30 minute treaty in which you cannot attack them. During this time you an build up your eco, army, research techs etc. Let's take an open land map like Arabia.

What would be your strategy for this scenario?

I'll start off by giving my idea:
Research spies. This is the only scenario where this tech would come in handy. Since the enemy vil. count is low at the start, you can opt to build a castle straight away and get it for say (5 enemies * 10 vils. * 200= 10.000).
Pick a civ that has a strategy thats easy to pull of by a noob player. Goth infantry spam, Frank paladins, briton longbows.
