Well it's sort of optional you can be creative and build epic buildings landscapes towns city's or you have the survival aspect that can be made more difficult with hardcore mode you have the server side to the game where you can play with the best gaming community (FACT!) basically as it a sandbox game you can make it what you want to be there are people that do adventure maps people who make music and people who are patient and precise enough to build scale replicas of famous buildings
Survival mode consists of staying alive but attempting to get to a place called the ''End'' were you must defeat the boss whilst doing that you must remember to eat and upgrade you armour tools and weapons a fight off the monsters such as creepers, silverfish, enderman, skeleton archers and zombies. I will have my own let's play out soon you will have to check it out ;D
Yeah, my kids and nephews love it to bits. I can see the appeal, an open world environment where you can build anything you like. It's kind of the equivalent of when we used to build a den in the woods. Just this is in the front room.
I don't know anything about all this Microsoft points. It's 1600g or something. What ever that means.
