I have 20 bucks, which should I buy, Magicka which I played the demo and had so much fun, Dragon Age 2, which I can buy off my friend for 15 bucks, or Civilization 5, which is on sale on steam(btw I loved civ 4). Please don't bother telling me how different these 3 games are, I know. But from your experience, which one would best suit a casual rpg/fps/rts pc gamer like me?TFC_Flamery
