Nothing makes me happier.
I wish they don't do another game, but in the matters of deserving a rest... they just made the worst game in Bioware history so all they deserve is to work hard to redeem themselves from this major failure. But... since I know they are not able to do anything good because the ones that made DAO great are out of this disgusting company, I hope they rest like you said, except that I want it to last forever.
Well, that's a little hard, even for a fan of the DA series like me, who is definitely, in the "I truly disliked DAI" team.
I don't think DA will end with DAI (I should say "I hope not"). There is a possibility they will take it very slow this time regarding a future title for the series. I have no doubts DAI had a successful launching. I mean, the hype was very palpable. I was so hyped myself, I even convinced one of my colleagues, one who had never played video games before, to buying the game. So you can imaging that being utterly disappointed with DAI and in so many levels, wasn't easy. I'm not sure if it was the long list of things I didn't like about it or the depth of that dislike about some of them but this is the first time since I started playing Bioware games that I barely finished one playthrough (and I really had to push myself to finish that one) and never looked back to the game.
I prefer to see the glass half full so I will hope DAI sold good enough to give a next DA chapter a strong chance to be developed. I don't really care how long it will take. I also hope the devs will reconsider regarding this new large number of races as options for a protagonist and that also, once and for all, stop catering to already dated platforms. IMHO, the first has shown that not even an extra year of development was enough to prevent that feature from sucking big time/resources that otherwise could have been used to release a more finished game, a less rushed ending, given more depth to the main story, more connected side stories and a more developed protagonist and not having to fill an otherwise great game with an inane amount of the most boring fetch quests. the second one, greatly limited the devs from implementing so many features that they were forced to cut later on because those platforms couldn't supported them.
Dragon Age lore is an exceptionally good one and I hope it will keep us, old Bioware fans and many new ones busy for many years to come,
