Quantity does not necessarily imply quality. In fact, some times, and especially with games, just the opposite. The world doesn't need any more POGs or Beanie Babies.

I'd say it's definitely a full game. So many hours of fun and tinkering even with the relatively low scroll count so far. And it's just going to get better, still Beta.

I very much recommend trying out Scrolls if you're into deep strategy games.

I'm surprised you think Scrolls is a deep strategy game. I've only sunk no more than 10 hours and I already see everyone with the same decks (3 factions, 3 decks). Not much room for different strategy since there are hardly any cards. Scroll's complexity isn't 'complex' - it's needlessly cumbersome and tiring - having to do consistent mathematics in your head isn't fun (for me anyway).

Hearthstone is way more complex simply due to the 9 (vs 3) classes.

I have played it for around 2 months and still find new things to play, test and learn. The hex grid not only makes the game unique for a TCG, but also enables a lot of tough strategical decisions.

3 factions yes, a fourth on the way. 3 decks? No way! Decks evolve constantly and new ones pop up, some die out - seems very healthy for such a small, young game so far :)

Just my 2 cents and experience.

That's the same thing I say about poker. Not nearly as complex as Apples to Apples.
