I personally don't know. I "was born" where people were even fooling around if they player with cavs, bolts, siege towers or walls. So I was really weirded when alpha 23 was released because I had to learn again how to play in 0ad, and it wook me a lot of time. So, I really don't know why we passed from a rule-based alpha to a everything-free new alpha. ANyway, I personally prefer games with no rules, because they are more realistic and also more funny
