Unicron, because Sega, and more to the point, Yu Suzuki, puts ALOT of time into making their games be the great looking, great playing games that they are.
To tell you the truth, when Namco released the T4 pics, I thought I was seeing VF3tb pics with different pics. And that was on the Model 3 board, 4 years old.
Sega can do alot with the medium they are given. Namco just rushed the product to get it out so it could compete with VF4 in Japan, which it never really had the chance to (look at the charts)
long live Yu Suzuki!
