Since the Baldur's Gate series, Bioware have only tried the open world exploration twice again, the first being Mass Effect and the second being Inquisition. I don't think Origins or Jade Empire were open enough to qualify. Either way those titles didn't capture the essence of the Baldur's Gate series in what they achieved with its open regions which had story and quality content in them that made them rewarding to explore.
Inquisition's open environments looked unique and effort clearly had gone into creating them but unfortunately the aesthetics were just a veil over what was really just a barren wasteland like with the worlds of Mass Effect.
Give us reason to explore these open regions. Fetch quests and resource collecting is not just repetitive but boring too. Occasionally in Mass Effect we got a quest on one of those worlds that had a story, that's what we need more of. I'd like to see side quests in these open regions that somehow relate to the story or are a side plot on their own.
I haven't played the new Mad Max game but its vehicular control is what maybe Bioware should aim for with the mako: mindless fun. If I'm going to be on some nearly empty planet then can I at least have a car that can drive fast rather than one that is a chore to manage? The mako itself can be improved with how it feels and controls. I want it to feel heavy when I'm driving it, perhaps it can even smash through natural structures but the versatility comes in when it's able to drive up uneven cliff-sides and propel into the air.
