The reason he built it off the video game is because the video game came first--so the question is, "why did Lucas allow two different v-wings?"
Besides, Lego already made an imperial v-wing, so he had to build the original for it to be a MOC. :)
WOW! good job, man! its been a while since iv seen the REAL v-wing. I hate the fact that they ignored the fact that there was already a v-wing but decided to throw in the name again anyway for the imperial v-wing... again props dude. excellent work!
