The only bad part about this game is that it's too easy to distribute illegally. It's not obfuscated in any way.
I feel the same way about minecraft.
A bunch of kids were huddled around a computer at my school, so I went to check it out.
One of my friends was playing Minecraft, and bragging about it and stuff. Turns out, he had it on a USB and was using a Pirated Copy, and just doing the offline trick.
I told him to go buy the damn game, and that he shouldn't even pretend like he was one of the first kids at our school to know about it.
