Not a Halo fan, and unaware of Sunset Overdrive, but WOW, what a back-log. Enjoy, mate. Especially the Metros: probably the most atmospheric games I've played in the shooter genre in a long time, with only the original Bioshock surpassing the indirect world-building methods that those games employ, imo.
As for Bethesda, yeah, I don't really mind too much: I understand that they wanted to keep the plot under wraps, and it doesn't detract too much from the rest of their ace presentation. But yes, Bethesda's NPCs aren't really at par when it comes to player interaction or character depth, and they'd be perfect if they could address that issue. I had high hopes when Chris Avellone left Obsidian a week or so ago: I really wanted to see him at Bethesda, writing the dialogue for the NPCs, making more memorable quests similar to the ones in FO and FO2, and creating somewhat more memorable side-characters than the standard Bethesda fare (Boone in F:NV, for example) . Sadly, that didn't happen, but hey, here's to hoping.
And as for Inquisition, I liked it. Not as much as I liked Origins, but it certainly contained enough interesting characters, party banter and stunningly rendered locations to end up feeling like a worthy use of the 50-odd hours I put into it. It does feel a bit rushed at certain points in the main quest, as you'll likely discover yourself: but it's still got enough to pass muster. Personally, I long for the sort of dialogue we got in Planescape, Baldur's Gate and Baldur's Gate 2, and the colorful characters that accompanied said dialogue: but you're right, these days games sell copies without needing that level of detail and dedication to crafting characters, so we're unlikely to see those times again. Plus, voice actors: can you imagine the cost of a voice actor voicing all of Morte's lines?
If there's one thing I realistically hope to happen, however, it's Bethesda allowing multiple companions and perhaps scripting some banter between them. Dragon Age was vastly improved by this: all three games had endearing moments of characterization caused by the party members occasionally ribbing each other behind your back, and it added up to more than the sum of its parts, imo. Overall, it shouldn't be too difficult for Bethesda to try something similar, even though naturally the list of possible companions for their games tends to dwarf the small cast Bioware usually employs. We'll see in November, I guess.
