I didn't care for the beginning of Fallout 4. It seemed really repetitive and rote, and I hated ... hmmm.... just in case.
Toward the beginning a major mission if fighting with the minutemen and they just give you power armor and laser weapons.
To me a big part of what makes FO awesome is earning the high end gear, so just being handed it right at the beginning really turned me off.
Turns out that was misplaced... you can use that stuff, but have no way of repairing or replenishing it, so it quickly becomes unusable anyway.
The really great parts are all the stories... primary game story, companions, and just the random crap you run into by just exploring. There are also several endings... 4 I think? I made a save right before the end so I could replay them (though I screwed up and wasn't able to do one of them).
