Not necessarily. Do it like EA, which only sell you the license to play their games, not the game itself. You can play it on their rules and on their DRM. Playing EA games is like paying for a library book, which you can keep until the library says it wants it back.That would be illegal in most (if not all) countries anyway.
If Paradox was evi, they would...
...intentionally cut 50% of the Gameplay to sell it as tiny, overpriced DLC´s
...forcing you to use a third party Program like Origin
...use forced Online Activation
...force you to stay online even when you play in Singleplayer
...reduce the overall quality of their games while even the slightest improvement would be advertised as a technological innovation
...90% of the budget will be invested into ads/trailer/teaser/bribing the Press
...release their games primary for consoles while a PC conversion takes up to 9-10 months
...use SecuRom as DRM
...make sequels on a yearly basis which little to none improvements
