AnotherGame is a mod for ToE 3.1.

5000 on a hero is no joke right now.

And who was it that told me that 5000 for upgrading a mine is very little, especially when a similar warehouse costs that much?

What you're going to do with warehouses/mines will ultimately be much cheaper than the option I suggested (mines at 5000), which you called "too cheap." And it's in this form that there's a risk of mass mine upgrades.

Yeah, I thought about it, and I would actually make it free.

No comment. Maybe then it would be easier to switch to G6 if you like free conversions so much?

Not at all. I just respect Urgash more, for political reasons.
