OK, if he abandons some of his silly ideas; like ponies.....
Quite honestly, I don't think ponies are a bad idea. Look at the diverse mount system that Mount & Blade has; that works well. Maybe not the random modifiers like "swaybacked" and all that, but at least with some basic different types of horses.
'course, since most of the battles we've seen in Frogboy's games have involved no horses at all, it's probable that Stardock has a vastly different idea of the importance of cavalry, compared to myself and Xia.
tl;dr: I want ponies too.
