Fallout 3. I never made it out of the vault on my first play. It's long and slow. I played at a friend's house who was past that point and realized I needed to try again. I'll never regret giving it another try!
It took me forever to want to play Skyrim because the beginning is so dull. Not really a fan of the Oblivion / Fallout 3 / Skyrim openings. I can’t remember Fallout 4… I feel like it was a little faster.
