Since I'm lazy I will just copy my agotcards post here: Yes they are still worth money but I have no plans on selling them just like this situation. In the end it sucks my old cards are going to be worthless but whatever I have a common player set of almost every mtg cards from 4th-Innastrad that I don't really use but I dont feel bad about that either. Also as someone who didn't read the books and probably won't ever read them things such as there not being a general good Eddard or Robb stark kinda annoys me even more so that as a Greyjoy player that competitively I would never run a Balon outside of a winter deck and until recently Theon just never made the cut in most decks. I have partially just been wishing they would change the rule that attachments could be played on setup so I am extremely happy that will be the case in the next version.
So many of the changes are things people really wanted in this version of the game but somethings like moribund would cause huge problems and require tons of knowledge from erratas if changed. This makes perfect sense to restart the game. However while I still enjoy playing it becomes more and more obvious that things need a change and not something a FAQ can do. I started with netrunner but this quickly became my favorite LCG.
I put a lot of money into this game and love it. I got a complete set of cards 6 months later. I fall in as one of the not really new players but far from old.
