Block Story vs Colony Survival
Block Story
Block Story allows you to truly enjoy an adventure of a lifetime as you set off on your noble quest to save the world by combining the popular sandbox/exploration genre with elements from an RPG.Complete a variety of quests, explore and discover wonderful new biomes, build strongholds to stake your claim on a piece of land, mine for materials to craft and/or upgrade your gear, and even battle challenging boss monsters for a chance at some glory and fame. You can also set up your own farm as well as tame and ride on the backs of magnificent creatures, including a ferocious dragon.
Not to mention, unlike its Steam/PC version, Block Story is free for your mobile! Yes, there may be some waiting time involved, ads and even in-game purchases, but all of these are just some of the things the developers have to add in just so we could enjoy the game for free. Of course, if you decide that you love the game and would like to show your support, you could always buy the full game.
Colony Survival
Colony Survival is a voxel-based town-building simulation game that emphasizes on ensuring the survival (and expansion) of your colony of people, be it by making sure they have enough food to not starve to death or by stationing enough archers around the parameter of your castle walls to repel zombies. Like Minecraft or any sandbox games, you are free to build any base you like (underground, in the sky, or a proper medieval castle with a moat and a drawbridge) as long as you've got the materials (a.k.a. blocks) to go with it and there are various crafting stations which you can build and then assign a worker to just so you can create better and more advanced items.Aside from its infinite, procedurally-generated world, the game also uses an advanced 3D dynamic pathfinding system, allowing you to funnel your people along a specific path simply by having the necessary designs. The same goes for the zombies which usually come out at night to besiege your castle and your sleeping populace. As long as the zombies can't get in and slaughter your people, you can keep expanding your population and your kingdom to whatever size you like!
Colony Survival can even be customized to whatever difficulty you like, depending on how well you think you can best the zombies. So, if you enjoy Minecraft-like games but you also happen to enjoy a "build your own maze", tower defense-like gameplay, then Colony Survival game is definitely for you!
