My mistake, Bethesda was the publisher and Obsidian actually made New Vegas. Still, it's a similar gameplay mechanic, and some lessons could have been learned. Companions in Skyrim are boring pack mules that get in the way. That are semi immortal. Meaning they can sort of die, but usually not, and will just happen at the most inopportune times. To be clear; companions sometimes do block the doorway, but it doesn't mean you're completely stuck, it's possible to sort of push out past them. But the point is, you shouldn't have to bother in the first place - it gets annoying after the Nth time.
I like the game for the huge map, exploration potential, all that nice stuff. But they've been talking how characters are now vastly improved, and I don't see it. A bunch of polygonal uglies that don't do much.
