In principle, video games are lawful entertainment means as Sharia don't prohibit playing or having fun, since the Prophet (PBUH) used to say to Aisha (May Allah be pleased with her) during weddings (What means):" "O 'Aisha! Haven't you got any amusement (during the marriage ceremony) as the Ansar like amusement?" [Related by Al-Bukhary].
However, a person should be aware of the following matters:
First: Severe addiction of video games especially for those who used to play such games will be the cause of health and psychological damages, mental exhaustion, inattention of their obligations and useful accomplishments.
Second: The encouragement on gambling and betting.i.e. playing a game that involves gambling/winning or losing money even if it was indirectly, is impermissible.
Third: Shooting private parts and being indulged in prohibited acts.
Fourth: The game isn't one of the spy games that are globally banned.
In conclusion, if the game didn't involve the above deviations and was a mean of lawful entertainment then there is no harm on selling the above account. And Allah knows best.
