I'm all for ratings, though why not use the MDC to let all of you guys rate? It averages all the ratings, so you could use that... on the other hand, its outdated, and my totally rad fix (wait for it!) won't be out till early July...
For the record, my ratings on a few (I don't rate military because I know I'd be biased for sure):
Megapack 10/10. While not every individual faction is perfect, there is a wide array of so many good ones in very good quality. Thats a perfect 10 in my book.
Dark Magic 9/10. All that hard work has paid off. Now if only they'd stop using some of the magitech icons... And why is the magic behemoth making a retextured appearance here?
Dwarfs 8.5/10. Despite some balance issues, the dwarfs is gorgeous and very nicely made. My rating might be outdated though, because I don't have the latest version, but not ALL that many changes from mine to the recent...
Romans 8/10. While not quite as graphically good as some of the others, I found this very fun to play. Some units feel a bit expensive, and I found it slightly overpowered, but very good mod all the same.
Nihilirian: 8/10. I found this to be very well modelled, especially since it was one of the first of its kind. Gameplay feels pretty mirrored between the factions and nobody can pronounce (least of all remember) the unit's names, but hey, its fun and original.
Science: 1/10. Why 1/10? Because I didn't have the heart to give it a zero... Badly sized units, joke moves, unfunctional parts, and lack of balance all add up to a bad score from me (can we go into the negatives?).
