@wild_rodri We put out a blog with more details about this recently! https://www.ageofempires.com/news/return-of-rome-everything-you-need-to-know/
Originally, the Romans weren't going to be added to ranked at all and as a result weren't programmed as such, but they'll be added to ranked in a future update thanks to community feedback!
@Gianpi1990 The original Age I campaigns can be enjoyed in Age of Empires: DE! For Return of Rome, we expanded on the rich storytelling the era offers by creating three new exclusive campaigns focused on the Romans, Sumerians and Macedonians.
⚠️ We are aware of an issue where some installed mods are causing crashes in Age of Empires II: Definitive Edition. There is also an issue where some UI mods prevent multiplayer loading.
The team is hard at work investigating the issue and we'll update you as we learn more! http://pbs.twimg.com/media/FwR1_SfX0AE75Pg.jpg
⚠️ There is a one-time reset of certain hotkeys with this update, due to behind-the-scenes upgrades of the hotkey system we have also added to our Known Issues page.
If you run into this issue, you can adjust your hotkeys in the Settings menu under Hotkeys.
