I recently bought an used PlayStation 2 console.
I must say that for a device that was designed over 7 years ago it has still astonishing graphics. And now can be bought very cheap :-D.
Of course I bought Final Fantasy X - to have finally a PS2 and to not play in one (actually all ;-) ) of the FFs would be a sin :-D.
In FFX characters are advanced by spending Ability Points and various spheres on a Sphere Grid. I searched for a diagram of the grid so that I could sit down with a pen and plan paths for my characters. I found this one. It has unfortunately a black background, so there is no point in printing it. I took gimp for a spin and modified it. Bellow is the result :-D.
