Fallout: New Vegas, because it's been like a decade and I want to play again, especially after watching the series.
Took a while for me to get back into it (and figure out the right mods and settings for me), and I'm still feeling a little bit of that overwhelming "fuck, there's maybe too much shit to do", but I'll just chill with it for now.
Edit: LOOOOOOL. Legion already hates me and I haven't even met (and killed) Caesar yet. Barely even started the main quest at this point, which I suppose is tradition with Fallout, to be fair.
