Still haven't tried Minecraft, but all those YouTube-videos and hype surrounding the indie title have made you want to give it a proper try before forking over your hard-earned cash? Well, Mojang and PC Gamer have released a demo of it, in which you can create a world and play with it for 90 minutes before it locks you out. You can, however, create as many worlds as you like. Everything you get in the full title is available in the demo, which you can download from PC Gamer.
Be warned, though. It's virtual crack. You know what they say - the first one is always free...
If you already own Minecraft, it might be a good idea to start it up and update to version 1.5. It has weather and stuff.
