A Minecraft world really comes alive with internet-based multiplayer, but the requirement for a dedicated host creates its fair share of problems for both casual gamers and parents worried about where their kids will play. Mojang is currently testing a subscription service, Minecraft Realms, that could put at least some minds at ease. Along with providing a consistent world, it will give the host strict control over who gets in; long-term plans should also include profiles with trustworthy mods already installed. The developer hopes to launch betas for both desktops and mobile devices around May, with rates between $10 to $15 per month to keep a world going, but only the owner would shoulder the full costs. We imagine that there will be at least a few takers, both among families and those who want to safeguard their elaborate masterworks.
