the things i honestly love about fallout 4 are
the power armor literally feels like a tank. i love it.
the downtown boston and surrounding area are gorgeous, open world, even though a lot of places do not have a map marker. also, the glowing sea is definitely fun to stomp around in with power...
new vegas is awesome ill agree, but im still a huge fan of fallout 3. I thought it was a decent game. Out of all the fallouts, i wish there was another tactics made. I seriously loved that game.
i honestly believe that obsidian has already been working on the new fallout and just keeping it under wraps like they did with fallout 4 and new vegas. Todd Howard knows how much money there is to be made by letting obsidian do a spin off, they would be more than willing to do it.
