it's funny how people don't really bitch about minecraft :o
I'm actually kinda mad Notch keeps raising the price. It's a good game but I would never say its even close to polished enough to make the 20 dollar mark for an indie game. 20 dollars for an indie game, you better be getting some polished quality. Minecraft as of now is really glitchy and really isn't all that original either. It's gameplay elements consists of mining stuff and building stuff, that really only goes so far, especially when all you have to build with is large cubes.
I have a feeling the adventure update will make it more worth while, but I also have a feeling it will be full of bugs that need to be fixed.
