Once Set 3 releases I would love to see them release compiled Players Manuals separately. I don't mind getting the sets individually as they come out as a GM, but a complete ruleset manual for players that can be purchased separately is a no-brainer I would think.
For the most part I really like AGE as a system and a complete rulebook for GMs would be great as mentioned above. I would even consider buying a complete Dragon Age Game Master Manual once everything is out so I could have one book with all the rules at my fingertips. They could cut all the adventures and whatnot from them and just focus on world lore and rules.
One of the biggest problems I have with the way the individual sets are released is that when new sets add more rules and options to players to existing material, it makes some of the material I've already purchased less useful.
Case in point: the GM screen, I love it. It's got nearly everything I need for quick reference as a GM and it's one of the best I've used. Until Set 2 came out. Added Combat Stunts and the new Exploration and Roleplay Stunts (which I think are rather stupid and not intuitive) make it harder for me to keep up with players that have the cards that were included with Set 2. One of them want to do the All Out Attack stunt. I look at my GM screen, where is that? Oh, right! It's new...
I understand why they do it, and I understood going in that this was a work in progress. But again, some of the additions I really don't like. I'm actually strongly considering not using the Exploration and Roleplay Stunts altogether. Why take Roleplaying away from the players? Exploration stunts I'm less opposed to, but even some of those require that if the player rolls doubles and uses stunt points, as the GM, you suddenly have to give them more on the spot. More info, more loot, you name it.
Anyway, I didn't mean to turn this in to a rant. Just some things I've noticed as the Dragon Age system has 'evolved'.
