Usually goes like this:
"Oh, youre playing Minecraft? I wish there were more bosses. The dragon is a joke."
>Agree: "You know what does, though? Its called Terraria.... ...."
>Disagree: "What are you building? I wish there were more materials to build with. I can never get my stuff to look good."
>Agree: "I like how many choices Terraria gives you.... You never seen it? Oh. Well, theres like 40 different kinds of bricks alone....."
>Disagree: "Hmm. Maybe Im just all over the place. It would be awesome to paint blocks you put down, dont you think?"
>Agree: "You should see the kinds of stuff you can make in Terraria. Ever hear of it?...."
>Disagree: "Watch out! Creeper! Too bad theres only like 10 different kinds of monsters. Terraria however...."
That is how it starts out.
Then I tell them, "Yeah, it is fun to build the tallest castle in all the land. But thats about it. Nothing to really explore for (hate horses. Never bother with horse armor and such) except diamonds and then what? Make a badass sword and beefy armor? I want to see magic spells, guns, and all that noise. And I hate mods.
Goes from there. Yeah, I describe it as Minecraft Plus. Its much more sophisticated. I KNOW ITS NOT THREE DEE!
