Where Jonk says " a lot of time and effort that most of you don’t think about, and really shouldn’t have to" I think that is the problem. Gamers think they know what goes on behind the scenes and think they know more about what happens than the devs themselves.
At the end of the day the judgment should be kept simple. Will I get $5 worth of enjoyment out of these 7 cars in the dlc? Will what I see on my tv screen make me happy knowing I have spent an extra $5.
The judgment should not be “some clown pressed a few buttons on a keyboard saying “import from FM4” and charged us $5 for it”. Because at the end of the day we don’t know if it was the clown or the full circus (no offence intended, but laughter is).
