If I get a bid of 12 or more for allies, i definitely think an IC in Egypt is worthwhile.
I think bids are far outside the scope of this specific conversation, but since you mentioned it, I think that the way you use bids by adding extra units to the initial set up, ruin the game balance in earnest and are both moot and lame. At the same time. In a slightly derogatory way. Now if you play against real men, they will probably offer the US NO bid, which gives US extra NO money, distributed each and every turn. This money will not come to effect before Turn 3 or 4, so they will not ruin the first Turn set up balance. IMHO anyway, not alway but sure in Norway.
And in this case, the Persian factory is more worthwhile
