Pros
I haven't worked at Nexon in awhile, but while I was there: 1. Backing of the well funded Asian arm ensured the company wasn't shutting down overnight. That counts as a blessing these days. 2. Effort to be create a full fledged publishing operation created new units and focused on improving many aspects of current operations. 3. Like-minded, passionate people who you bond with because you are going through a traumatic experience together and spending more time with than your significant other.
Cons
1. Pay was mediocre 2. Work/life balance was not a consideration. If work to be done, it needs to be done. 3. The import of employees from Korea plus hiring of locals caused a fissure in the org that really wasn't justified. Nexon is tough on everyone equally. 4. Leadership lacked experience in running a company.
