The english translation was a bit confusing so I've sent an updated version to the developers. I'm also not sure what to do with the .deb packages - Perhaps I should find some server space where I can make my own .deb repository...
I noticed when Balazar starts up it says:
* Balazar * (Psyco not found ; if you are using an x86 processor, installing psyco can speed up Balazar a little)
So I went and found Psyco - a JIT compiler for Python. I remember reading about this (or a similar) project a while ago but I didn't realise it was ready and working. An apt-get install later I guess it's running in the background! I think glChess was slightly faster but I'll have to investigate more in the future.
Oh Balazar Brothers is basically a mini-game spin-off of an RPG called Balazar. Haven't got that to work yet though as it tries to write back to /usr. Naughty!
