I wonder how many of us actually do.
Edit 1: Oh and on to a question stemming from that: What is your opinion of people who spend/do not spend real money on NX? Should people who spend/spent real money have more benefits than those who did not?
I personally feel that they (the ones who do spend real $) should get more benefits than those who don't; especially those who've spent thousands. The game wouldn't exist if it wasn't for those willing to invest their earnings into it.
Edit 2: Also post how much real money you've spent in total since you've started playing (even if you currently don't play or on hiatus).
Edit 3: In hindsight, I should've added an "I don't want to buy NX even though I can afford it" or an "very rarely" option.
