Unless there's some kind of permanent DLC pass bundle available at launch, I'll try* to wait for it to go on sale for ~$40 before buying the base game. Do Paradox games ever even offer these kinds of options? I know they offer bundles like this for older games, but what about new ones?

*the amount of playtime I've gotten out of the original, even before DLC was available, means there is a very good chance I'll crack.
