So, my observations as a neophyte to the genre: Endless Space does not have a gentle guiding hand. I haven't played a true 4X game (having used that term twice now, let's define it: eXplore, eXpand, eXploit, and eXterminate), not since the old days of Master of Orion, and I'd barely even consider what I did with those 'dabbling,' much less 'heavily investing my play-time in them.' It's not that I didn't enjoy playing it, but I didn't really have context for what to expect from it.
Imagine my frustration, then, when Endless Space landed in my lap and I was told, 'Okay, review it.' I'm far better at tackling things linearly, proceeding from one obstacle to the next and surmounting them in turn. I've never been comfortable thinking on that large or broad a scale or multitasking with that degree of efficiency. Don't get me wrong I love attempting to play in-depth strategy games, especially if they're turn-based, but it's just that: an attempt.
