There are a few things I would like to see for X-Wing that would be nice to haves. I am sure all of these have already been said a number of times.
Posts. I would like to see 10 pack or 20 pack posts for sale. I haven't lost of broken one yet, but having spares would be good. I know you can write them for replacements, I know I have extras from the ships I am not running, but still it would be nice.
Acrylic templates and tokens that are not third party or just for winners of tourneys. Yes, I can get them 3rd party, but they are not officially sanctioned. Yes I will probably order from Cog'o'Two in the very near future. However, it would be nice to procure what FFG has shown they are capable of producing. My comment isn't meant to cheapen other's achievements at winning the special goodies, just a wish that they were available for purchase.
As for the cards, I can fully agree with what people are saying. FFG has pioneered the living card game, so applying that to X-Wing would be a very nice addition. All the upgrade cards in one set from each wave as a purchase option. I think that would be something people would buy based on what I read in this thread. I think it would be fair for them to offer that yet leave the pilots as ship only.
Lastly on my nice to have wish list, all the missions in PDF format. I like to use my ipad for all the rules content, and I would love to see FFG publish the missions in PDF as well. I have at least one of everything, and as they introduce more missions, it would be nice to see it collected and posted.
