You're trying to reason with someone who thinks that the sidequests in DA:I were amazing because they had no cutscenes or dialogue options so that you could make it up yourself and imagine everything in your head...
And if you try to challenge that by saying that it was a major shortcoming in DAI, he throws 130+ GOTY awards in your face as some sort of validation that it wasnt so bad cause others thought it was GOTY. I mean, what competition did DAI? There was no Halo 5, Fallout 4, MGS5, or Witcher 3 to contend with. DAI had what......Watch Dogs? Assassins's Creed? Alien Isolation. None of them carry the hype that 2015's big hits do.
And yes, the quality of compeition does play into the prestige of the award. That is why in college football, the 3rd place SEC team usually gets a higher national rating that the 1st place WAC team cause the quality of competition in the SEC is much higher.
And like someone said, despite the financial success DAI was for Bioware, 10 or 15 years from now people will not look back at DAI and say it was a gamechanger in the industry the same way Mass Effect 1 was or Skyrim was. It will be seen as a game that was good for the period in which it was released and thus rewarded for, but nothibg more than that.
DAI cannot even break 90 on Metacritic and GameRankings(professional reviews) but 2015 hits like MGS5 and Witcher 3 all have 90+ average metacrtic and gameranking professional review scores.
