I voted Egyptian. I have a lot of respect for that tribe since it took me months to pass 'Echo of Light'. In fact, I don't remember which level it took me longer to pass, Echo of Light (Egyptian 5) or Fall and No Life (Taxing 21 on the Megadrive). They both have extremely crafty tricks. I also like the graphics in Egyptian and Medieval, and Space as well but the levels are annoying. My least favourite is probably Cave.
