If you need more then one player character in a certain quest ( like the valves in the tanker quest) or want to roleplay more then one character then grab a friend and do it. 
This discussion has btw nothing to do with the topic, please return to the original one.
Solar, Izual, this suggestion thread is useless because there is no real reason, why not open another 2 subforums (and ask players, who have minimal rights to make a choice in 2238)
Example of quest mechanics i need 2 computers:
Imagine stituation, than NPc chars are replaced by players = PC. There is classic quest system: you go to PC 1., some chat, questions,.. then you go to PC 2.,... . I need 2 computers for reason, that i need to control, if every players who are talking to PC2 were already talking to PC1.. Imagine situation, that there will be 20,50,100 players names, you will have to ask again and again. Also there are russian nicks...
And many more, if you did not tried this kind of content replace, you dont see the problems and you say, use friend. It is not possible. Howgh. So your llimiting antialting have side effect in this ways.
