I really liked the game, it's nice to have this kind of coffe break turn-based tactical game (give me turned based and tactical battles and I'll pretty much always be happy), and there is a lot of potential here (more units, spells, a simple capaign editor?) so I was pleseantly surprised with the "end of book I" text at the end, as it suggests more is coming. Is that already confirmed, or just a possibility, if the game sells well? Any word on when it might be coming?

I as well, but I hope it is included with the base game, as of now there is not enough content to justify the price.

I agree, it would be nice if it is added to the base game. I was surprised when the credits rolled as I was expecting the game to have been longer. That said, I did enjoy the game very much and am looking forward to Book 2 :)

Braveland Book 2 (aka Braveland Wizard) is out on Steam and mobile now, and hopefully will be on GOG soon, especially because as-is the only way to get it on Windows is on Steam. (It's a separate game, not an expansion, it looks like.)
