I grew up playing ccgs like MTG and L5R. The main issue I had with L5R ccg was the snowball effect, and this game does an amazing job of fixing that issue. I hear people complaining about value of the core box and the fact that you need 3 cores to play competitivly, but at just over $30 per core, it is amazing value. For $90, you get 3 of every clan card and multiple neutral cards for other decks. For competitive games, this is still on the cheap end for price of entry.
The art and theme are both amazing in this game, and you know it will continue with FFG's amazing production. The games can run a bit long (45-120 minutes), but I have never been bored during my games. I cannot recommend this game enough, one of the best of the year!
