Big population cap = macro eco boom fest. You shouldn't do tactics with an abundance of available resources and population space. It's a trade-off that's not worth the extra APM. In short, this isn't Warcraft 3. It's beyond even the StarCraft's level of macro.

Not to be negative, but the main goal of the tutorial should be to show players how to have a gameplay that isn't totally lame. I've really enjoyed maybe two or three 0ad games of the quite a lot I've played, which were those where I've been able to do actual tactics rather than just farming and grinding the enemy down... Maybe it's me, but it's probably a quite common experience, especially for newcomers.

Indeed. The Corvus ship (or tech) should be way more efficient at boarding, but not the only way to board, as it was a common tactic of the ear.

There is a new RC at https://releases.wildfiregames.com/rc/ There are small changes to the Germans and the warning in on the summary page has been fixed.

The filename is: subtropical_islands.xml But I tried also with a map I called mediterranean.xml which had the same problem. Edit: The Map is named "Subtropical Islands".
