Dragon Age: Origins will always be "good for what it is."
What is it? A porn game?
In the context of when it was released and the relative quality of the other RPGs released around then it was a good game.
Compared to the broader scope of RPGs in general I still think it is decent (depending upon what you're looking for) but hasn't aged as well as it might have.
It offered greater choices with more consequences than previous Bioware games and although the RTWP combat system wasn't particularly inspired (the combat mechanics felt a bit like how a single-player MMO might play (mostly based around an aggro system with little in the way of tactical positioning)) it offered occasionally decent enemy design, some fun encounters (along with plenty of dull trash fights), and some decent areas to explore. It was possible to break combat in numerous entertaining ways if you knew what you were up to (stacking dodge items to make yourself immune to most physical attacks, unkillable arcane warrior and bloodmage builds, etc) none of this 'every build should be balanced and equal' tripe.
Additionally, I can't remember a game that came before it that had unique first chapters depending on the choice of character background and occasional locked content for those backgrounds later in game. On top of that it had some of Bioware's better companions (none of Morrigan, Shale, Dog, Lilliana, Sten, or Oghren annoyed me by being in my party and offered occasionally amusing banter).
From a design perspective, I think it's probably Bioware's most competent game (world building was decent before taking a huge nosedive in Inquisition, art was mostly good, in-house ruleset is just about passable) and parts of the story were interesting (more the political bits in the mage tower, and in the dwarf and human kingdoms rather than the archdemon/blight plot).
I'd give the game 6.7/10 so just managing to keep it's head above water in good. I have some lingering nostalgia for it and I might be forgetting how bad some of the worse sections were (I remember the forest part being annoying, and some of the repeated encounters in the Derp Roads dragged on past their welcome). I doubt I'll get the motivation to try and get it to work on my relatively new PC in the near future to check though as apparently it can have issues with modern systems.
