I'm looking forward to this. I like MageKnight (though I very rarely play it), and feel the best quality about the game is how cheap it really is to play!.
Mass combat requires large numbers of miniatures (a pain), and hopefully the price will be low enough from WotC so that this new line will be playable.
Random packs? Hmm... I'll wait until I see them before judging whether or not this is a good move. It might have the effect of bringing the price of the entire line down, and of course you can always buy individual figures on the secondary market - the MageKnight secondary market is extremely affordable.
Here in Ballarat, most of the common MK figures retail for aus$1 (about us$0.50) - if I wanted a group of 20 orc figures, that'd be very affordable. Compare to original Chainmail prices, where it'd be somewhere around aus$100. That's one-fifth the price!
So, here's the pros and cons of the Random factor:
Pros:
* The entire line is cheaper, because they don't have to worry about some figure runs not selling.
* There will be a secondary market which will allow you to buy common figures very cheaply indeed.
* You'll be able to get a lot of figures cheaply.
Cons:
* Difficulty in obtaining the one figure you want.
* Some unique/rare figures will be a lot of money to buy on the secondary market.
Personally, I think the random run may well be an excellent idea. It's also better for retailers, as they don't have to gamble on individual figures that might not sell.
Cheers!
