Aground vs Urban Dead
Aground
Aground is a 2D, side-scrolling, survival-themed adventure game where you'll be digging out the bowels of the earth for precious ores to turn into tools, weapons, and armor or to sell to gain coins. Similar to games like Kingdom: Classic or its sequel, Kingdom: New Lands, the game will have you venture out to explore new islands to discover more about the story behind the land, to meet new characters and to obtain better resources to craft superior items.The storyline in this game is pretty intriguing as well. It features a Bermuda Triangle-like area where people often get shipwrecked and are washed up to one of the shores of the small archipelago. The islands are filled with weird creatures and is rich with minerals and resources. As survivors starting from scratch, they do not have access to the technologies they used to enjoy that is until apparently a mysterious tribe, called the Mirrows, helped to set stuff up.
Aground offers players the sort of freedom that Minecraft is able to provide and yet, is not fully a sandbox game nor does it have a procedurally generated map. Of course, this game has a great storyline, along with quests to help drive those plot points forward, and that alone makes it a really fun game to play.
Urban Dead
Urban Dead is a mainly text-based MMO game set in a post-apocalyptic city that you can play straight from your browser. Assume the role as an urban survivor trapped in a quarantined city just trying to get by. However, unlike most games, Urban Dead is an MMO and as such, you'll encounter other players as you wander from place to place hoping to scavenge something - anything - that might help you. These players can be friendly or hostile (though, it's more often the case the latter).You can even set up a center of operations, so to speak, by clearing a place out and lock the place down. Other players might try to break into your base though, so it might be best to recruit a few trustworthy players to help you maintain your base and keep it as well as everything you hoard in it safe from any looters. Of course, there are also zombies that will attack your base and you, if you are unlucky enough to bump into one or an entire horde.
Urban Dead is a quite different text-based game admittedly, but it is still very addictive to play. It might be best to play with friends though due to how its base building feature is structured and well, there is always safety in numbers.
