Block Story vs KoGaMa
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.
KoGaMa
KoGaMa , like Roblox, is a sandbox game that should actually be called a games platform rather than a game itself since its main two purposes for existing is to let players create their own games without really needing to learn how to code and to let other players enjoy the games they have created. It is free to play and is completely browser-based. Its creation interface is easy to use and there are plenty of fun stuff, such as guns and toggle switches that you can add into your game. As evident by the enormous volume of community-created games, the game can turn out to look very magnificent, voxel-wise! The fun that these simple player-made games provide as well as the hilarity of seeing cute voxel characters running or jumping for their lives make Kogama-built games incredibly enjoyable too!If you're looking for an alternative game for Roblox, KoGaMa is possibly the closest match, though Roblox players may enjoy games like Trove, Blockland and, of course, Minecraft as well.
