There's a bit more to that story, I'm afraid. Turns out last year, after NCSoft banned his Lineage II account for RMT, he sued NCSoft for $12 million, alleging fraud, unfair trade practices, defamation, and emotional distress.
In short, he claimed they committed fraud by banning him without cause.
The suit was dismissed due to lack of jurisdiction. He later amended the suit to establish jurisdiction, and added allegations of gross negligence; it is this amended suit that accuses NCSoft of, basically, peddling addictive product without proper warning, and shutting down Lineage II accounts to encourage players to shift to Aion.
The charges of fraud, unfair trade practices, and intentional infliction of emotional distress have been dismissed, leaving only the claims of negligence and defamation.
I certainly doubt he'll have much luck proving the claim of defamation, since that charge is based on NCSoft calling him RMT; in the US, truth is an absolute defense against charges of defamation. Add in a few other facts, like:
1) Reading through the suit and doing some simple math, it turns out the "account" in question is actually three accounts, and
2) He claims 20,000 hours of accumulated play time over a span of 5 years. Just for reference, 5 years is 43,830 hours, of which the average person spends 14,610 hours asleep. Nevertheless he somehow found the time over that same five-year span to sue the City and County of Honolulu, the US Army Corps of Engineers, and a private developer claiming they had improper permits for the construction of a marina,
and it's looking less and less like a simple "disgruntled gamer wants payback for wasting his life".
