Board Game Arena

Hmmm, I was pretty hostile to this idea but an auction for picking wonders is actually an interesting idea.

Or, if coins are very needed for some cards they can bet points (stars)

I've always said the easiest fix for Hali(B) was to make it so that the built in "resource" wasn't a commodity that could build a science. That way it slowed down significantly how fast a Hali player could get all 3 Tier 1 sciences and the likelihood of getting all 3 in Age 1 was much smaller (but not impossible depending on their neighbors).
