As someone who has worked at paradox for a long time I feel its time someone stepped up and told the dark sad truth.
Yes, its true. back in 2007 before the release of EU3, we spend the last couple of month chopping off all of the expansions. The art programmer complained a bit when we downgraded the map as part of cutting out Divine Wind and some are still not sure if that was a good call, but of course how else would we have been able to squeeze every last dollar out of our customers??
In fact, one of the reasons it took so long to get going on EU4 is that we had to wait for Johan to crash all of the paradox sports cars before we could be allowed to get off the couch and work again. Dont worry though we spent over a year cutting out DLC from EU4 before release so I'm pretty sure we can just lazy around for another couple of years now!
