Star Wars: Empire at War has been updated to 64-bit 17 years after release
Here's a nice surprise for you: Petroglyph has updated its strategy RTS, Star Wars: Empire at War, 17 years post-release.
The update mainly allows the game to run in 64-bit, but it also fixes some minor bugs, applies some balance changes, fixes out-of-sync issues with multiplayer, and stops some behavior issues with units (thanks, RPS).
With the update to 64-bit, you should no longer encounter Out of Memory issues. There have been updates made to several maps, graphic assets, and core functionality of some of the units used in space and land battles.
