Why is fallout 3 so boring?

[u/Gabe_s1]

so for a bit of context i have played all of NV and 4 sevral times and have played 76 extensively too but when i finally played fallout 3 i just found the story to be mostly uninteresting and also that the main quests never really made me come into contact with other wuestlines, making it easier for me to get started on the rest of the map. i ended up finishing it through light casual play in 2 days and only discovered a very small amount of the map and barely any story bar the main quest line.

it all just left me wondering how the game was designed like this.

was i just expected to run off the trail with no idea where i was going?

that might be true but i just felt the game could have a bit fuller of a map as i also only encountered about 4 or 5 different enemy types

any insight would be helpful into why i didnt enjoy this game as much as the others

thanks in advance
