Talk:NegaPosi Twin Towers/@comment-4418057-20130218173400

Originality: B+ (Often, I have seen negative and positive twins, but the upgrades are good enough to bring this from C to B+)

Details: A ((Don't really understand the trap, but everything else is good)

OPness: B+ (Stuff should cost a bit more, and why is the second upgrade $5200?)

Overall: B+ (Good, but a few upgrade changes could make it an A)
