Fallout 4 does everything you want in a game. It has great combat and exploration. It can be crazy and serious at the same time. It is a truly special moment in gaming.
It is amazing how the combat is 100 times better then past fallout games but it still doesn't loose its RPG feel. The new crafting system is great for guns, and armor. This extends to settlements which may feel slightly clunky but you can create some awesome things.
Another improvement is the dialogue system which resembles The Witcher 3 but in Fallout you get to craft your character into anything you want him/her to be. Everything is intertwined with gameplay; that means no more menus when looting or picking your dialogue option.
The graphics are very good during the day but can get kind of ugly in different weather and times of day. It doesn't lesson the experience at all though.
There is so much to do and competing factions. Not to mention just getting distracted and exploring. Unlike other Fallout games this one is densely populated with either people, quests, or things to explore.
This is only scratching the surface of what a masterpiece this game is. This was a rushed post but that's only because I need to play more Fallout 4!
P.S. I may write a review but that will probably take a while! I haven't even completed everything in New Vegas and that isn't for a lack of trying! Fallout 4 is also the reason for our absence of promised Uncharted reviews.
