As many have already said in this thread, it's pretty useless trying to determine one game as absolutely the best, as all games in the DA trilogy have their merits and flaws, with features in both list changing depending on how is making those lists. For example, personally I can easily name several things DAI does better for me than DA2 and vice versa. However, as the features DA2 excels in, again in my experience of the game, are also features that are more important for my enjoyment of the game and that is why for me DA2 is a better game than DAI. It still doesn't mean in anyway that I don't enjoy DAI. Also, I don't quite get why it would bother anyone if someone else enjoyed a game they didn't.
Having written that, I kind of have to comment on how DA2 fans just can't seem to win. When DA2 came out, you couldn't make a positive thread about it here at BSN without having it turn out to be extremely hostile almost instantly due to a bunch people who felt it was their sacred duty to make it clear to everyone that the game was an affront to all things good in this world. Now that DAI is out and people are bringing up what they may have enjoyed in DA2 more than in DAI, there is a lot of comments basically saying it's a trendy thing or people just looking for things to complain. Which to me is really weird, as the comparisons to DA2 have been nowhere near as toxic as it was when DA2 and ME3 came out, but that is of course just from my biased perspective.
On a side note, it has been great to have been reminded about the many Hawke quotes again. I had forgotten about their reaction to Cory's name, which was kind of awesome.
