For some people awards tend to validate their opinion. If a game (DAI , Witcher 3 or any other game you pick) wins a number of GOTY and/or People's Choice awards it validates in some minds that their choice was a good choice and there are like minded people who agree.
The awards and even nominations are kudos to the hard work that developers have put into their games. Whether you agree or disagree with the choice is another matter.
Each gamer has his/her own opinion. I (for one) fully acknowledge that Witcher 3 is a great game based on the awards it has won. My personal opinion is that it is not the game for me. Geralt is too much of a set character for my gaming playing purposes and the world does not interest me. I like to create characters of different races, breeds and colors. One of the reasons I have trouble playing Mass Effect.
DA2 came as close to a set character as I wish to get. DAI better suits my gaming purpose. I fully believe that it deserves all the awards it won that validates my opinion.
Everyone here has the right to like or dislike a game, film, book etc. The problem on many forums not just the BSN is that people get attacked for their opinions. Some posters try to speak as if their opinion is fact and try to speak for more than themselves. It is like if I want you opinion I will give you one.
I believe that civility is key to any discussion. I am always up for discussion. I have had many great discussions on this forum. I try not to engage in arguments.
