Why do I or must have Epic Game Overlay in stalled when I bought the game on steam

Reading the forums, we used to be able to get multiplayer achievements by playing private matches with AI; is it still true?

Homeworld 3 does not exist. It never came out.

I played this like a year or two ago and had no issues (same PC). Fired it up now (EPIC) and the main menu just taunts me because no input works from any source. What gives?

The extremely minimal resources, the fact your resources and units carry over between missions (they don't even start you with free Salvagers), and the fact the ai cheat by generating unlimited units at no cost mean it's not just possible, but in fact very easy to hit a point where you simply can't win the mission you're loading into now matter what. Whose idea was this?...
