The Gamecube ones address Neji. But it's all done in the whole "You've done the attack combination now watch the code." Also, I think the newest one on the Wii addresses the Sharingan (same thing for this).
I figured the game devs avoided both of them, in the sense of how the abilities are shown in the anime. I had an idea on how to approach the sharingan tho, using existing game mechanics. I'll have to wait for a beta invite from Raph to see if it works. Well that and some actual game making knowledge
ahh. well I'm actually not playing any Naruto games. The anime is a guilty pleasure (well the good arcs anyway ), but I never bought any of the games out of fear they wouldn't match my (possibly unrealistic) expectations. Sounds like I made the right call.
