- My research online beforehand indicated that X-Wing was a more solid, better designed/balanced game, and had slightly better quality components.
- The store owner said basically the same thing when I talked with him about it, and he also said that X-Wing tended to have more players (at least around where I live).
- The X-Wing miniatures look nicer; better paintjobs and more to scale.
- I knew that I would want to get my friends into whichever game I picked, so I'd have some people to play with, and they much prefer Star Wars.
I was left with the impression that Attack Wing was basically a slightly worse, cheaper (in terms of quality, not price) knock-off of X-Wing, so I decided to go with X-Wing.
I guess my last major concern would be balance. I've heard lots of horror stories about WizKids atrocious game balancing, power creep, event exclusives etc.
This all sounds dead-on to me and mirrors my own research which led me to the same conclusion - that X-Wing is the better option. I know one guy in our game group who has ST: Attack Wing and he tells me there are not many players around here either.
If you are going to have time and budget for another game, my advice would be to get into a significantly different game which also has a great reputation rather than a weaker clone of a game you already have.
Personally I would suggest that you look into some of the LCGs or Doomtown: Reloaded (basically an LCG but they can't call it that since FFG has the term trademarked). Then you can have another highly competitive quality balanced game with a reasonable cost. Feel free to PM me if you have questions about any of them, I've played them all.
No idea why it's so popular at my FLGS tbh...I can only assume it's because they are used to the similarities to heroclix. The more I learn about it, the less I understand why X-wing is getting so little love.
Some people just like to be really competitive with the best builds maybe AW offers that where the balance of x-wing does not.
Maybe they saw the prequels and it forever ruined SW for them.
