Yeah, I played it at the time. It was pretty tough, and I needed a walkthrough later on. Pre-patch, the game wasn't very approachable, to be honest. The patch added shit like a simple hint system, and cursor highlighting when pointing at usable objects. Brilliant graphics, though.
Epsilon: Game is great btw, I love it, so far it's a definite goty. It's remarkable how much has changed since the beta, stardock have been working their asses off, and it shows.
