In my first post about this, I joked about "fighting the good fight with Steam recommendations". Honestly, though, this is what should ultimately be the point of this activity, in my opinion. Sure, through our initial recommendations, we establish our taste in games, so you put a bunch of classics and Top 70 games there. But going forward, I think we should think of the curator as a means of giving more exposure to less popular, but nonetheless good RPGs and RPG-likes. Underrail is an obvious example of a game like this to me, or Expeditions: Conquistador. We've already had some complaints over recommending Dark Souls, but honestly, Dark Souls is so popular already that a codes recommendation or lack thereof changes absolutely nothing - putting it on the list merely informs people of our preferences rather than affect the game in any way.
Now, whether Early Access games should be recommended is a separate question, and at first glance I'd be inclined to say no, but it might be worthwhile to discuss.
