I'm not complaining that you do, I'm pointing out that you're objectively wrong in doing so.
I don't believe expensive watches, shoes or pants provide enough extra quality to justify the expenses of (at best) 2 to 10 times the price of cheap version and (at worst, in case of luxury watches and designer clothes) up to a hundred times or more.
Consequently I don't buy these things. What you are doing is going to the store, seeing a vastly more expensive product that promises a longer half life (which Paradox delivers) and better quality end product (which they also deliver - their older games are some of the very best gaming experiences I've had, albeit admittedly expensive if bought outside of sales), buying it, playing it until you grow bored and THEN complain about the price after being informed about what you were getting and how much you would have to pay for it.
I'm also not impressed by people then pointing out that that is not AAA behaviour when many of those same people bash AAA games for fire-and-forget product practices.
Most of those threads don't even say the game is bad, they are more along the line of "I enjoyed it but want free stuff because (insert sector/AI complaint or pet peeve bug here)".
The old adage to this is vote with your wallets. If a product looks like it's not worth the money, is packaged with stuff you feel you wouldn't buy seperately or comes with bothersome terms and conditions, you don't buy it. Buying it, getting what you paid for and then nagging about the price is just petty.
I'd be as outraged as some of the naysayers if Paradox sold Stellaris as the full, final and finished product and then tacked on DLC out of the blue that clearly contains extra stuff where there shouldn't have been any, but the only one to blame if you buy a product after full disclosure is YOU for making the decision to buy it in the first place.
Nobody went into your house and strong armed you. Ninjas didn't hold your family to ransom in a cunning plot to have you buy a long term investment against your will. You saw the product, you had the opportunity to look at Paradox's product history, speak to customers via the internet (so much easier than in the past when you still had to actually FIND someone to ask if they truly liked the product) and had several full gameplay streams available even PRIOR to release.
Anybody who has access to all that information and still cries that he's been duped needs only look into a mirror to find the guilty party.
