Yeah it will be hard to follow and deliver after the 1st. The trailer looks sort of consoleish, hopefully they focus more on story than graphics unlike almost all modern games.
What was funny about the 1st was that it launched with HL2 engine before HL2 launched
Nice story, plenty freedom to choose your story line and play as you want not having to fit into a predefined strict storyline. Similar to how original Deus Ex had freedom of choice that wasn't cosmetic but offered replayability to explore more options of the story.
Linux... couldn't care less unless somehow they prove that the same code runs somehow magically faster with Linux kernel and Linux drivers, most games don't and actually run slower on Linux than Windows... if they run at all.
