Actually, if you like Fallout then go play the other games but not this. Also skip the Android mobile Fallout Shelter because it takes way too much time before you actually get into late game = over a year.
There is few story elements but after story is played there is nothing else to do than buy atomic shop items and show off your doll house called player housing about stuff that wont change the feeling of games gameplay experience any better or more fun.

Most of nice looking stuff is not part of the story but microtransaction shop item gimmicks that cant be found trough story or questing and earned that way.

Spend time somewhere else to meet people or play trough the other fallout games like Fallout 1/2/3/4 and new vegas.

And then the older review:
----------------------------------
If you like Fallout 4 or Fallout 3, then its most likely that you like this game also. At least it looks almost same.

"War. War never changes."
And then they changed the whole gameplay experience in Fallout 76

Main quest cannot be continued until you reach level 20. So there is level cap.
You are doing other quests and exploring the world while getting to level 20 so that is not a problem.

For me the game somehow went like this: Its no longer the exploration like previous games, finding something new and having to loot almost everything until you have enough materials to craft your own ammo and where your main story is part of series of short stories and side quests. In Fallout 76 it was almost something like getting your camp up, getting vendor up, going to quest for 10-20 levels while filling almost everything to vendor and your player vendor, then leveling to lvl 30, then getting .50 cal and figuring out all ammo is expensive and spending every perk card to get better ammo factory while spending every bit of piece caps to steel and other materials to craft ammo.. hit lvl 50 and it almost got easier until you figure out that monsters got stronger while you got heavy gunner perk cards to maintain that .50 cal so time to change to something else...

...until you get almost best main weapon ingame then there is no longer really need for anything better to do ingame. Unless you are into plushie and teddy bear collecting. And nice outfits for looks.

Game for those that like questing and exploring the world until for reach end game. Then it just grinding events for scrip and bullion, and crafting better legendary items while fighting legendary enemies.
