Kenshi vs KoGaMa
Kenshi
Kenshi is an open world, semi-sandbox, party-based RPG that offers players an completely open-ended gameplay rather than opting to force players to go through a storyline. You can be anyone you like in this game, be it an honest trader, an adventurer, a bandit or others. Scavenge important resources, including weapons and armor, from corpses and use them for your own. Recruit new companions from towns, build an outpost of your own, and grow it to accomodate more of your companions. Of course, as your little town thrives, bandits and jealous rivals will attack you and you'll need to make sure all your people have what they need to defend the town and repel the invaders.Sounds like fun? Well, it definitely is. However, Kenshi, being a pretty ambitious early access game, does have it fair share of flaws. The game still has plenty of glitches still and can be really hard to get into, especially at the beginning of the game where you literally have no idea what you need to do.
That said, the game is very unique because it has a pretty rare theme and its gameplay - a combination of party-based survival/ base building - is also oddly rare among the other games on the market. So, you might want to check this game out.
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. Do check it out!
