well I guess many players wants to play with several char, but for now it's really complicated to share stuff between two chars. And not everybody wants to share base with others etc.
so two options:
- add option for a char to invite another one in his room through computer or NPC. (would be more convenient, but decrease base interest)
- find a way to give stuff to an offline char through NPC
current possibilities : use sandboxie or a trustful friend if you have.
