I'd definitely buy it! The sequel is coming in a couple of months, but the original is fantastic. Don't hesitate to cash in on it!
I couldn't get passed the tutorial of battleheart. I like a game I can pick up and play not have to be explained to the end of the earth.
If I remember correctly the tutorial is super easy, explaining how you draw lines to the enemy to attack and draw lines to your other characters for healing etc.. Then there's the specials at the top which are just buttons and finnally you get to the equipment shop, Tavern and skill selection charts Inbeetween The levels. And yes buy it...
