While we already knew that the original Age of Empires will get a Definitive Edition and this one will launch on October 19th as an exclusive for Windows 10 Store, Microsoft has now announced that both Age of Empires II and III will also get remastered and get support for 4K/UHD resolutions, better soundtrack, and plenty of gameplay improvements.
In addition to these remastered Definitive Editions, Microsoft has unveiled a big surprise for Gamescom announcing that Age of Empires IV is under development at the Relic Entertainment studio. While Microsoft did not provide a lot of details, Relic's post says that they will try to fuse historical context with deep strategic gameplay, bringing back the franchise to the forefront of gaming.
Microsoft has also published a trailer and Relic says that more details will be revealed in the months to come.
