If you play City of Heroes, City of Villains, or even
Lineage II, this is the cheapest way you're going to find to do it. The price Amazon lists on this game card makes it substantially cheaper than even the discounted rate you would get for subscribing to City of Heroes/Villains for an entire year at a time via credit card. You can enter as many game cards as you like into the system at any time and they will each add two months onto the end; you do not need to wait for your account to expire before using it.
Note that though the game card's box has the City of Heroes logo on it, it can also be used for City of Villains stand-alone, or apparently any other NCSoft Game such as
Lineage II or Auto Assault. I'm not sure why Amazon is offering the City of Villains branded gamecard at full list price but this one so much cheaper; the only difference is the logo on the box.
Yes it works for L2 also.
