Now that WRD (or WyRD, as I shall now christen it) has reached open beta, I took a look at the decks...
Wow! They've certainly bumped up the nationality choices. Aside from new countries, there's also coalitions now, so there's a scandinavian coalition, a Merkozy coalition, an anti-MacArthur coalition, that sorta thing, so now you can have your cake and eat it when it comes to nation choices.
Also, the time period decks are set in is more strict. You can't combine units from the 70ties with units from the 90s anymore, it's either pre-1980, pre-1985, or post 1985, adding more grueling choices even before you've started actually building the deck in the first place 0_o.
EDIT: WELP, incorrect.
