It takes a few hours for each design. So, if I can manage a few uninterrupted hours, I'm happy to do it. Weekends are rough though. That's for the girlfriend. : )
As for faves, IKASAME has been the favorited the most. I'm not sure whose an official CKC entry or not when I do these, but in terms of faves, IKASAME amassed the most of those. Granted GAONAGA has been up 2 days and is almost 100. Not that any of this matters.
Here's a wiki for the game, and, more specifically, a link to the wiki page with all of the current progenitor monsters (with more in the future, including today, as it's Monster Monday): kaijucombat.com/wiki/doku.php?… Then there are the sponsorship monsters that get cards, SPN1 and SPN2 (cards for SPN2 will probably be available sometime in February in the Sunstone store). Or you can go to Matt Franks DeviantArt page *KaijuSamurai
Yes, I'm not certain it was out when I originally obtained zBrush. It's sorta like a bare bones version of zBrush. Like what Photoshop Elements is to Photoshop Full. I've never used it, but from what I've seen, it's possible to create amazing things with it. Definitely try it out!
