Kind of interesting I wound up liking Bionicle Heroes on the DS, and in some ways more than the Xbox version. The DS version had paid attention to certain details of the villians, like Zaktan being made of nanomachines or something of the like. As minimal as the story was, and even though it wasn't exactly cannon, it had much more story than the console version. The environments weren't half bad either, especially for a handheld game at the time.
It's that Barraki video again!
Wake me, can't you hear me calling...
Out of darkness they come crawling...
For some reason those lyrics are still stuck in my head, but there's no trace of the differential equations I was trying to put in there at the same time.
I never did get a copy of Bionicle Heroes. Probably because of those equations.
