I used too. It wasn't my account though, and the person didn't know I was using their account. No harm in that though, right?
I played Survival for a while and built lots of stuff in creative. I expanded villages to cover a whole biome. Then I would back it up then spawn a bunch of withers to fight iron golems (the policeman lol).
I got bored pretty quickly though, even though it was fun.
Go on townie in scottland studios. IP: Play.Scottlandstudios.com
I love townie. It's the perfect place to tp to people and kill them with a diamond sword. PvP is the best! Just have full enchanted diamond armor and diamond sword. Also strip mining is easier in towns because usually mob spawns are off in towns.
ive only played pocket edition and the ps3 version for a few days. i actually downloaded pe on my phone just today. its ok i guess?? i keep going to creative and loading new worlds where theres a village near the initial spawn point so i can refurbish it and make it look nice.
