'computer company's concern' is the definition.
I can't judge whether this definition defines the answer.

'sorting gamers into types' is the wordplay.
'sorting' indicates an anagram.
'gamers'+'into'+'types'='gamersintotypes'
'gamersintotypes' anagrammed gives 'OPERATING SYSTEM'.

Can you help me to learn more?
