2. I've never been impressed by a terrain made out of bricks. This partially goes back to a problem I have with landscapes in Minecraft - You can't walk over them smoothly; you have to keep jumping your way up them and falling down them. I hope a set of large ramp bricks changes my mind about this, but smooth rolling landscapes as far as the eye can see was nice to just move around in, let alone actually build and play in.
That's the thing about Blockland - it's more than Lego, where there are more than blocks to build with. Blockland has more than that, you can practically build with anything and make anything.
