This seems pretty safe. Just make sure that the workers build roads on the forests so that they can go to the forest and chop in 1 turn. I hope some of the other teams aim for other wonders.
Also what free tech do you plan on getting? I would like Metal Casting or Code of Laws. If this were single player, I would probably consider other techs but those two look like the best so far.
Any idea what the time Oracle usually gets built in multiplayer games with skilled players?
I like Code of Laws over Metal casting because of our cheap courthouses versus expensive Forges. Furthermore Colossus doesn't seem very useful Wonder at the moment.
I've no multiplayer experience, but I suspect that all or most of the teams are doing similar tests as we're. So I wouldn't have high hopes on getting Oracle especially because we've "bad" starting techs (no mining and/or Mystisicm). We probably have one of the best commerce capitals at population 5 (assuming no gold,silver or gems in other capitals), but against other financial leaders that edge might be quite tiny on getting to Prieshood first.
