It's not for everyone. But what makes it fun for me is simply creativity. Build. Explore. Mine. Survive. And of course it's blocky, that's the style and charm to it.What is it about mind craft do people like? I've never played it.
Trust me, I used to think it was over-hyped back when it was only on PC. But then I bought it when it came to the Xbox 360 for my fiancée and I tried it out and was hooked. Ate my own words.
As I said, it might not appeal to you. Everybody is different. I think there is a demo for it though?
