I'm hooked, it's not as flexible as NWN was when making things but what it gives in return for that lack of flexibility makes it much more enjoyable. I remember posting earlier on this blog how I was looking for something to not only be fun but challenge me to think and be creative. Minecraft has accomplished this nicely.
I've been doing the single player survival game ever since I purchased the alpha. While I've not built anything massive except a mine shaft and a large mining area square shaped at the bedrock of the Earth. I'm slowly figuring things out and trying different things.
I'll post a screen shot of my mining project as well as other shots later on. :)
