Hi, I’m from EU, switched steam to US- New York and found many servers during morning hours in Europe. I know it’s possible to switch it off although it depends on steam, because Age of Empires 2 HD was in the same situation at launch and people were extremely unhappy. They have switched region lock off entirely and added a ping sorter/filter to the servers instead and to this day there are a lot of servers at any time of the day. Homeworld could have many servers too if you did this.
Btw, I didn’t experience any lag at all in the few games that did get pass the “downloading content” doom with players from US. So pings were fine, and even if they weren’t, this game barely has any micro so it’s not that much affected by a little lag.
