9 Phenomenal Video Games That Cost Absolutely Nothing

8. Fallout Shelter

Who'd have thought that Fallout Shelter - considered, at first glance, at least, to be little more than a side project pieced together to drum up hype for Fallout 4 - would eventually go on to outlive the latter's relevance?

Bethesda's support of the post-apocalyptic sequel has long since come to an end, but it continues to bring new content to the little mobile game that could, itself stealing away the precious few free hours of many would-be Overseers.

In a lot of ways, Shelter's main appeal is similar to that of EA's Sims, constantly requiring players to babysit its Vault's inhabitants, care for and train them until they're ready to re-enter the cesspit that is irradiated Boston to scavenge supplies and go on adventures.

Whether they return with untold riches or get themselves eaten via transit by a Deathclaw doesn't matter. Everything, including your Vault dwellers, is a replaceable cog in the machine to build the world's biggest Vault.
