It is possible actually.. (one of you will have to host the server)
You need to play via LAN on the same network.
You need to log into both pcs with your account.. This will unlock offline play.
On the one your friend is using you sign in but with some random name.. the option will appear asking to play OFFLINE. From there you just log into theI P of the server you are playing onEnjoy. --- XBL GT: Soren Wildheart PSN: deMunoid
You will log in with your account name so you will be visible with that name. If your friend/nephew types in a name it will default to the name PLAYER because it will recognize that its not registered and give you that default name for offline play on that pc.
If you want to play with 3+ people you will still need to log in w/your name initially on each PC to unlock the OFFLINE option.
PC 1 - your ID PC 2 - PLAYER (default)
If you attempt to log in to a 3rd PC using the PLAYER default one will get kicked off.
on the 3rd+ PCs you will need to use a program that modifies the Java String for the name PLAYER to a different name. There are instructions somewhere in this thread or on a different forum. Since I have multiple accounts I dont remember the steps but it IS possible for LAN/Offline.
Hope this helps. --- XBL GT: Soren Wildheart PSN: deMunoid
Just remembered, its called the Quick memory editor. If you google it with minecraft you will find what you need to make it work. Sorry for the late post I forgot all about this until today. --- XBL GT: Soren Wildheart PSN: deMunoid
