To be fair, when I heard Mojang was coming out with a game called Scrolls, my first thought was "huh, wonder if it'll be anything like The Elder Scrolls."
Now, while I don't necessarily think the lawsuit is the right thing to do, I'm also not a lawyer, nor am I a game developer. Bethesda has been one of the better companies out there, certainly better than EA or Activision. I enjoy their games consistently, and have since I started playing Morrowind on a computer that could barely handle the graphics at the lowest possible quality (I now buy my computers based almost solely on the thought, "will it be able to handle the next Bethesda game?").
As much as I love Minecraft and Mojang, I can see the reason why they're doing it (even if I don't agree), and I love Bethesda games. If you're going to base all your purchasing habits on things like this, then you really shouldn't be buying games from EA, or Activision, or nearly any big publisher out there.
