I'd say no. Or rather, wait for a big sale (I hear EA is cool with cheapening their games like that nowadays). Personally I found DA:I to be deadly dull (and I actually enjoyed DA:2 despite it's many, many flaws because it had really good characters, gameplay was decent enough and I liked the less grandiose story. I'm sick of being THE CHOSEN ONE, hero of the land, only you can save us yadda yadda, boring!. Hawke's more personal story appealed to me).
I have 2 major problems with DA:I : The whole open world thing is about 90% fluff to 10% actually cool stuff (at least from the little I've played, but I've heard it doesn't actually get better, despite all the "get out of hinterlands" advice). It reeks of aborted MMO and there are a lot of gameplay concessions made to encourage you to explore (because otherwise you'd have very little reason to). The main story is gated off until you get an arbitrary number of points by doing side stuff. They tried to contextualize all the fluff, but it all goes to shit when you find yourself Head of the Inquisition, Chosen of Andraste, Closer of Rifts and Collector of 10 Ram Meat (from rams that respawn in the same small area every 30 seconds or so).
The other big problem is the combat, which is downright insulting: It lacks any real depth: you have the typical tank/rogue/mage trinity, but it's all for show because the enemies are too numerous, CC/taunt abilities are too short and few and it all boils down to spamming your abilities and hoping the enemies drop before you do in a big, disorganized clusterfuck. ZERO strategy/tactics involved. It's poorly balanced (pick the right skills and you basically get an I WIN button in the form of one spammable ability that does massive damage, has no cd, insignificant resource cost and gives you a shield), the companion's AI customization is so bare-bones that it might as well not be there. In fact, it's pretty much like SimCity 2013 - is built to give the illusion of depth and hide the horrible flaws for as long as possible. It mimics the combat of DA:O with some of the more action oriented stuff of DA:2, but fails miserably to deliver on both fronts.
Which is all the more a shame since the characters seem to be the best in the series and the story also seems to be quite good. But the moment to moment gameplay is just so horribly dull that I just couldn't put up with it.
How something as broken as DA:O could get so many accolades is beyond me.
