'Fallout 4 is an open world action role-playing video game.' - Wikipedia
The lore in Fallout 4 clashes well with the post-apocalyptic, 'wastelander' theme. In primary and secondary social encounters a player is granted the opportunity to pick from one of four responses; 'sarcasm' is common amongst the selections, as well as a more direct 'yes' or 'no'. After you've made your choice, a scripted conversation entails between the player and the non-playable character. There are also special choices that pop up sometimes, such as: persuasion for higher rewards, or to change the course of a quest. To succeed when choosing one of the special responses requires a high level, an amount of points in the Charisma attribute or in perks associated with Charisma. The terminals and radio pvssyr in game add to the lore and can bring clarity to some aspects of the story.
The graphics are fine for the size of the game and the amount of content. Bethesda Softworks have moved on from Skyrim and previous Fallout games with appreciable models, textures and animations for all characters. The more common vectors have a certain youth that will withstand the game's scope. There're plenty of nicely crafted enemies: sets of different robots, sets of different animals and more sets, though some appear more commonly than others. The emotional soundtrack of Fallout 4 is to be remembered, and the music on the radio stations are catchy.
The gameplay is impeccable, it's a perfect blend of a first person shooter and role-playing game. Apart from minor changes here and there, such as with the 'V.A.T.S system' slowing time rather than stopping time, the mechanics are the same as Fallout New Vegas, albeit lacking the hardcoe mode. A base builder system has been added which gives reason to scavenge pointless junk; you upgrade your bases using a freeform system with many parts you can add into the world, and then you care for the people there with shelter and beds, food and water, and happiness and defences. Scrapping items gives the necessary resources required to upgrade your base, weapons and apparel, or the new power armour - mentioned in prior Fallout games. A player levels up after gaining enough experience points through killing enemies, completing quests, exploration of the world or by special means, and each level grants the user a point to spend on an array of perks or base attributes.
