Many people said so much already so I will try to make it short
TFW offers nothing new in its multiple elements. Fantasy background. Turn-based strategy. Collectible Card Game. 3D sprites. Flux (mana/resources/others). Deploying, building, casting.
But what TFW offers is the original symbiose of those elements. I'm particularly happy with rather simple cards designs that give player an opportunity to understand and learn a card in just a few battles but the possible synergies between those cards open the gates to another, more complex and creative gaming dimension.
And that's it. As long as TFW will stay simple but give possibility to become more complex if players wish so, it will be playable
Nice graphics as well with use of young but potentially talented artists ^_^
