What is ignored: You build an Ice house and it generates 30 food in the first minute after completion. If you build an corral, it needs 60 seconds time to train the cow before it generates the food. So that is an ¨extra cost¨ of 30 food. Also your corral calculation assumes 8 cows per corral, whereas in the start of the game, you cannot afford 8 cows and you will have at the early phase only one or two. So the calculation assumes that initial investment is not a burden. So it is more like For the first minute after construction: 100 wood invested+build time, 150 food invested (for cow recruitment), no tickle After 1 minute: 100 wood invested+build time, 300 food invested, 1 food/s tickle. So after 2 minutes you need to consider: I have thrown 300 food and gained 60 in return, do I need to put another 150 food in it? I ran a spreadsheet and only when you get your 6th cow, you have recovered the food you invested. If you start your game with corrals+cows, you will see that the investment is not that good. A woman on a field does return her costs within 3 minutes. To be fair to the corral: goats give a better return on investment. What I would suggest is added functionality for the Ice house: namely being a drop-off site for food in addition to the tickle.

Haha, yes, it's true. The problem is that I haven't even finished the first civilization yet, lol. And I changed so many things in the game that the PETRA BOT is broken, so whoever plays won't find a real challenge.

Don't underestimate the power of testing  Releasing is always when you find the worst bugs Also I can help you with tooling like checkrefs to find broken / missing art files.

Does anyone know of other video´s that show the new A28 changes? I am curious.

From you, I expected more dedication to 0ad.
