Step-by-step explanation:
Nick is involved in an online gaming community, actively participating in chat rooms and sometimes playing games for real money. All these activities are conducted virtually, i.e., over the internet. Therefore, the term that best describes his situation is Cyberculture.
This term refers to the social dynamics and cultural implications brought about by the rise of the digital age. It encompasses communities formed around online gaming, social networking sites and other internet-based activities. While terms like 'Virtual Society' and 'Social Network' might also apply to an extent, they are not as holistic in capturing the full range of Nick's digital interactions as 'Cyberculture' is.
