I love the planning, WT. It's what is required to put the full power of WBE on display. Re: WBE > HE You're right that getting gold through fail gold is better than building wealth directly; although at some point you have more than enough gold and you've hit the one-tech-per-turn threshold (not sure if that actually happens on Deity Marathon though). I guess it's still better to get WBE gold and build Research than to just build Wealth though... I've found that when I'm keeping the slider at 100% by building wealth, near the end of the game when my big hammer cities switch to building space parts, I either struggle to keep the slider at 100% science or I'm not able to get that last tech in one turn. In other words, you can never have too many OF beakers as a safety net even if you are doing one tech per turn down the stretch. I'm talking in circles but that's because my head is spinning (haha) but I support your statement that "It will always be better to continue WB Economy than build wealth." ... as long as you have an AI finishing all of those late-game wonders for you.
