1 star? Come on people.. Don't you check a product's site before testing it? If you had you'd see this isnt a simple map drawing package.. You're giving it one star because you couldn't work it out in the few minutes you used to "test" it and lost patience. Then you looked for flaws. RTFM. >.<
The target audience is RPers, and often you need a lot of detailed maps. Graphic Converter is not a solution to the problem at all. Typical tabletop RPers are used to reading heavy manuals, so this is no big deal. It's complicated because it's powerful and flexible.
This app seems great for what it's intended, and any serious role-player would see it's value - the maps aren't ugly, it lets you edit the graphics! I've only used it for less than an hour and am seriously considering purchase for a campaign world and setting for stories I'm writing. $34 isn't too much for something as specialised as this, what else are you going to use? Nothing else on the mac does this stuff (that I'm aware of!)
