In 2003 it released a game made by one of its subsidiaries, Wizet. This game was MapleStory.Nexon is known to be a little bit "greedy".
Nexon America
Later in 2005, NX Games merged with Wizet to become what is now known as Nexon America. Since then, 4 additional games have come out for Windows computers, and as a result of the merge, it appears that the games are now updated more often and are in faster development.
Nexon Cash
Nexon Cash Is the buyable currency for Maplestory. It is used via the Cash Shop, can then be used to buy special items, such as- Clothes, EXP+ scrolls, pets, useable items (Chalkboards, VIP Teleport Rocks, etc.), and so on. Because Nexon does not accept donations, this is thier backbone when it comes to money to keep Maplestory and their other games alive.
