Unlike Obes I can play more than one game.
BOOOM!
Yeah FO4 is a blast. Could not be more pleased with it. They knocked it out of the park in every way that matters and a couple others. Still a little Bethesda buggy, but spam F5 and you will be fine. Alt Tab works fine and CTD is still around but rare.
They have added some nice new mechanics that add a bit of depth to it and the map thus far seems pretty huge. The leveling system, once you get the hang of it, is great.
You can use your WiFi Apple or Android device as a real world Pip-Boy and it works better than the integrated version.
Dunno how many hours the game has in it but I would guess in the 200+ hour range with plenty of DLC to come.
