True, a simple logo can work well, if not better than a complicated one. But going from a 3D-like logo with reflection (like it was chromed, get it?) to a generic, flat multicolored pokeball is not the way to do it.Rick said:
The old one is machine-like and almost intimidating. I think the improvement here are the new 'friendly' and 'pleasant' looks of the logo.
In graphics arts terms, the old one displays superior technical proficiency. Fancy logos don't always (And usually do not) make the best brand images though.
