No, it's just all their games. But especially Combat Arms. I only play it because it's free, I'm waiting til I have enough money to buy TF2. Anyway, they're only in it for money, Combat Arms is their worst game because they never even try to fix it's many, many problems.
i've been without Maple Story for too long. And I've heard Combat Arms is really laggy. At least, that's what it was like for my brother the one time he installed it.
