Should I buy Minecraft or Civ V: Brave New World?

So, my dad promised me to buy me any PC games if I reach the first rank in class. So I did. But I'm still choosing between Minecraft and Civilization V: Brave New World. And the problem is, my dad only allows me to buy one of those games. And I know I should save my allowance to buy the other game, but in the priority chart, which one should I buy first?

Plus, why do you recommend one of these games, and please tell me the advantages and disadvantages of each game.

Currently I use a PC that's installed with Norton Antivirus. And I'm afraid that Minecraft will be blocked by Norton. But in Civ V case, I know that Civ V won't be blocked by Norton because I installed the base game and God & Kings expansion.

Thanks.

Added (1). And I like both strategy and creativity games. I like the types like building stuffs like houses or cities, and then I can conquer other's cities. (That leans to Civ V). But I also like the game where I can create my own house, my own farms, and team up with my friends. (Which leads to Minecraft and The Sims series.)

Well they are both diffrent types. Minecraft is fun online with friends, while Civilization v is strategy, more about conquering other nations. You must pick what type you like.
