The factions are all boring. Permanent skills, with no respec options?! And for god’s sake, let me eat food on the ground by long pressing E.
Apparently that last one is being added with an update soon.
I think the factions are okay, but not nearly as good as their counterparts in previous games (eg. NCR > Freestar Collective, although that’s probably more thanks to Obsidian than Bethesda).
