Because a lot of people think that the 'quality' of the game isnt right because it was intended for consoles, and yeah, a console port may not have full directx11 support and extreme high res textures, but it still has the same core story in it.
They're not comparing between the same game in diff platforms, they are comparing the new console port game (for example DA 2) to it's former PC oriented big brother (DA 1). People say 2 has a completely different system(remember I have not played that yet, I only read about this), and people didn't like that system and stated that the change was a total fail.
A lot of people are complaining that by being more accessible to people, the dev often drastically change the ways to play a game that was once a classic. Not saying that it happens to all ports but it just seems that a lot of these ports have that problem.
I'm neutral on this issue, I hope you don't find my comments biased. I've yet to experience the issue myself, but I believe those gamers arent complaining for no reason when they say the new game system of so and so port is bad.
