Thanks for posting Mikiem. I remember Fallout Shelter was initially released just before Fallout 4 was released back in Nov 2015, but only for android phones and I think you had to have pre-ordered the game first to gain access to the download, which I'd done, but not owning an android phone, didn't get chance to play it. Although the game is free to play you can buy in game items for real money that although not necessary, do add to the game. Still, it's definitely worth playing even if you play it totally free. The Fallout franchise is one of my all time favorite franchises and am really looking forwards to playing game.
Fallout Survival is a bright and cheery game compared to Fallout 3, which although a fantastic game was very dull and grey for most of the game; virtually everything in the world was a shade of gray (see images below, however, soon after being released, modders released create free tree and grass mods that brought the game to life.(see the end of this comment to see comparison images of Fallout 3.
The commercial games focus mainly on survival out of the vaults and in the wasteland, whereas, Fallout Shelter is mainly about building a good vault. It's a side scrolling adventure that has over 2500 community reviews that are mainly positive. You do require the Steam client to download and install this game.

Fallout 3 map
original
What you see in the first picture below is only a small part of the world you can explore on foot in first or third person viewpoint; it only occupies a small corner of the fallout 3 map (see the the bottom right of the map image above). There are underground area's such as the metro stations as well as other places to explore as well. The surface environment is massive, with various communities spread across the map, most of whom you can interact with and affect the game in various ways. there are also hundreds of mods from graphic enhancements to new area's to explore, buildings, weapons armour and NPC characters to interact with..
