Interesting. Reno is going to win, you know. Even though Rikku has a higher polygon count, she can't out-do Reno's bad-assness. Tifa just looks kind of weak, you know, with all of the lack of polygons and color. Despite the fact that Rikku OR Reno could snap off her arms by those "skinny-elbows" like a twig, she still looks kind of tough. However, if this were an epic battle between the three, her toughness would be ended with a whack in the head with Reno's cool weapon. Rikku would probably start laughing at the low-polygon Tifa's head being flattened to a pancake and fall off the platform. Nicely done.
A- for good taste, but no plot.
