If you have it, do you think the game possesses longevity?

The important thing is finding a mouse that is comfortable to you, that's what really makes a difference.  Some people prefer heavier mice and some people don't.  The best thing you can do is to try it and return it if you don't like it.  Your adaptability will vary depending on how long you've used the Mamba for and how quickly you personally adapt to new things but don't fret about this, it really shouldn't be that big of a problem.

I play it. Its actual realy good and challenging. M+K work pefect too. Good Stawars Feeling. No Bugs  or Crashes. No Reason not to get it. I have around 10h atm and would rate it 8.5/10.

You should check out multiple reviews and some gameplay videos - there are some up that avoid major story and spoilers.
 
It looks good - I have no idea how long the game is - but there's certain to be some replayability. But it is a single player game, so the amount of replayability will be limited. If you're into stories and single player games, check out the videos and then if you like what you see, buy it.

Probably lower settings in ground war, it's probably just the size/scale of it. like a raid in an MMO.
