People emotionally attached enough to come to the forums to complain will stay with the franchise. The folks who really won't buy the next Dragon Age just uninstalled the game and went on with their lives.
Regardless, (in my opinion) I reckon the devs would be interested to hear from long term fans of the series who were having trouble maintaining interest.
(Edit: Because people who make art and entertainment surely want people to enjoy it. I mean, who knows? But, if I were making a thing and people bought it, I may not change it, or provide a refund, or apologise for it, if people, especially long term fans, disliked aspects of it, or worse didn't finish it, but I'd certainly want to know the why of it. I'd assume the devs would think this way, but like I said, who really knows?)
I struggled for a month with bugs and level design, while also absolutely loving aspects of combat and feeling a bit mixed on characters, was sad to leave the game behind when I went on holiday, but am now enjoying The Walking Dead and The Banner Saga on my laptop while away and remembering what it is like to be properly engaged and happy with a game.
I do understand that wanting to love it thing. I dunno what other game I would have put up with this many crashes for, not to mention walking across massive levels.
I'm not the person this was in response to, but even if I do shelve inquisition, I'm on board for the next DA thing. Who knows what will be next?
(Edit: my point being, people who may not entirely dig DAI may still be into the series, it's not mutually exclusive.)
