Why would I give donations to Paradox so you can get a game for free?
Because the principle of donation is to give for free will some money for something you want(in this case a gift for developing like Wikipedia*).
If perhaps the only way to help economically company Paradox it's buying products, then you'll be buying things that do not correspond with your primary motivation. So for all of us that we want Vicky2 or anything else developed would have to buy almost all the Paradox games, even those who we do not want.
doesn't apply to this situation at all. Paradox as a part of their warranty already released a number of patches and will release one more soon enough.
Yes it is true, however, the patches that have been released didn't yet corrected everything, and the game continues in many aspects unplayable. To percept this, just see the forum or the tips given by many, many players, and you will see how the metaphor of my furniture store corresponds with this situation, they were mending the situation, but the furniture was still defective.
I think that we have to find a good Balance like Aristhotle's.
My purpose is that people who have buyed HOI3 receive for free the expansion, and people who hadn't buy HOI3, need to buy HOI3 and Expansion. Don't forget that this community give much to Paradox
