I preordered because I've never been disappointed by Paradox games. EU4, CK2, HoI4, Stellaris, Victoria 2 (#gimmievicy3), ALL very very good games. PLUS it's only $50 NZD (like $30USD). Show me a 'AAA' title that costs literally twice as much that you'd get 1,000's of hours of game play out off?? Quality gameplay too, games like Destiny don't count because doing 1,000 hours of strikes to get the perfect roll on a specific shotgun is just stupid.
I got no problem paying $100 to buy a 'AAA' (insert Jim Sterling's voice here) game I know full well I'm gonna play through it, finish it in like 30 hours and never play it again.
So 1,000 hours of game play for $50 is a bargin. even if that $50 extends out to like $150 after DLC.... still worth.
I think some companies you should never preorder (looking directly at you EA), NEVER. But Paradox, meh, up to you. Their track record has been solid for making good games and I know I'm gonna buy it anyway.
All IMO of course, so calm your panties.
