I just got an idea and in order to realize it I'll have to open another two accounts in EVE online and there is one thing that I couldn't find out about this. Will I have to buy EVE voice for these accounts too or can the one I already have be used with all my accounts? Thanks a lot for your replies!
Each account in EVE online needs it's separate voice ( which imho makes perfect sense btw ) so I guess you'll have to spend some more money for this operation of yours. Still since you have enough money to open two more accounts I suppose paying for two more voices won't be such a big problem.
