'While you are using your perception thingy, can I purchase a few more tabs or screens?'
[Yes, you have passed the next stage of requirements for upgrading your system access. However, if I may suggest. Instead of buying an entirely new functionality, please consider expanding your access to the voucher merchant.]
Thinking for a few moments, Gordon was a little put off. Originally he had wanted to buy the craft merchant or some additional system space.
'Are you saying that I can only have one or the other?'
[Yes, your current level restricts the abilities the upgrade system is allowed to provide.]
'Is this one of those galactic law restrictions?'
[No, this is one of those, you are too weak to support more, restrictions.]
Sometimes the system definitely displayed a bit of personality!
'Okay, okay, no need to be sharp about it. I know I am just level one.'
