The current state of 0 A.D. on modern Windows PC is somewhat promising yet still unstable. 32 bit version of the game makes the crashes (out of memory) so often that it's not possible to enjoy longer gameplays or larger battles. Is there a clear instruction how to get already compiled 64bit version OR build 64bit version for Windows OS?

You could play on special maps

Strange, it's the second time somebody posted this. 

Hi! After updating macOS to Tahoe 26.0.1, some sounds—like unit commands and selections—stopped working. UI panel clicks still work, and the music is fine. I tried reinstalling all dependencies, reinstalling the game, and changing a lot of settings, but nothing helped. tried 0ad v27 and 27.1

It would make the random sea maps more interesting for me if, like in Delenda est, they created arsenals or additional coastal fortifications with space for ships to repair, but smaller than a fortress, a kind of naval port. I would make it a one-time option so that the coast cannot be blocked. I would also like to have the option to elevate an administrative center to a capital. Just from a purely conceptual perspective, a war should also have advantages, like gaining a new unit or achievement when you defeat someone. What do you think? Does that make everything more interesting...or too complicated?

Right now I can play 0ad like AOE, which is cool. Apart from that, I am more interested in playing battle mode (with military formation enabled) against my friends. I do not want to spend too much time on developing economics stuff.  Therefore, I am curious is there any config flags in e.g. 0ad/config/ can be applied for such setup? I suppose no. Or is it possible to configure and compile the source code so that only battle units are setup? Thanks

Sure, but this is an art task.
