Why do I need to play Minecraft?

There's so much you can do, build, create art (seriously people have made amazing structures and pixel arts), play with thousands of people, there's a minecraft "hungergames" among other fun multiplayer games, there are mods for almost anything, there are guilds, and there's mods about almost anything from TF2 to Portal to Doctor Who to Naruto and much more. The possibilities are endless

Because its a creative game and your only goal is imgaination its bassicly like legos but in a computer game

It's fun playing with your friends in minecraft but not alone
u create your own world there

I don't really play it much at all but its fairly simple to understand, and its adventerous. Suitable for all ages, i'd say it fits the ages above 17-18 bcz it allows them to explore or live a fantasy life/housing that they would like, for younger ages, its fun because you get to do whatever, you can be 5 years old and build your own home, its really just one of those few games that seems hit several age groups interest wise, and he's in his 20's, i wouldn't consider him a kid
