Yea, I'm pretty much hooked. I took a vacation and really started to get into it on the plane. Found myself staying up late on my vacation to play. I keep getting lost in the crazy amount of side content you can acquire/play. I want to recruit all the classic units from Spot Pass, I want to conquer all the challenge maps, and just keep going and going and going. Anyway, to illustrate the amount of side content I've been working on, I'm to Chapter 9, but I've clocked 20 hours of play time.
Also been working on pairing units. I've been a little unsure who I should pair with whom, but I've done my best and so far I'm pretty satisfied with the results. I still have some potential unpaired male units, but I think I've decided which units to pair with the females. It sounds like I'm breeding Pokemon or something...
The story hasn't really been a factor in my enjoyment of the game so far. Honestly, there hasn't been much so far and I still have no clue what is really happening.
Well, I better get back to it as I have to get back to work tomorrow.
