Are you a Sandbox Games fan, but do you want to do something more than just build buildings? Then RobocraftX could be the perfect game for you, besides being free (and in Early Access).
This game, even if it is simplistic to call it that, allows you to use your classic Minecraft blocks to create your games. Yes, that's right, it's practically a "game maker".
The guys from Freejam have released RobocraftX, even if in a fairly embryonic phase, because they strongly believe that the community can make a great contribution to the creation of single player, multiplayer, PVP games or anything else that comes to mind, ranging over many different genres .
The nice thing that you can create your game without knowing anything about coding, but only by putting your imagination and ability to use block construction in a creative way.
A beautiful project that you can find on Steam a this link.
