It looks amazing. I know I'm going to tinker around with it, I've been screwing around with developing tools for ages.
Having said that, Selnor: you are delusional. I hope you are on drugs. I want to be on drugs. I want to be on drugs while screwing around with Project Spark.
Project Spark will NOT be bigger than Minecraft. Most people don't enjoy creating their own games. Most people creating their own games are not nearly as able or talented as "real" developers. Project Spark is also very limited compared to making your own developing tools. It's not indie development when you have to pay royalties to Microsoft or whoever owns Project Spark to sell your Spark-powered games.
The game fills a niche. It is awesome. But Game Maker isn't bigger than Minecraft or all indie titles combined. So why would Project Spark be?
