Always loved their meaningful updates that bring meaningful features like this. These complex features take them months and years to implement, but you can't complain - they're 100% worth it.
@darthrevenx: In the end they gave up and just said screw it and bought Minecraft outright for $2.5 billion.
Having said that, I was of the same opinion as you, but tried Spark before it died and it's not bad at all - it is a VERY versatile tool that let people create VERY diverse games.
