At best, its ~$28 bucks a month, at worst its $50. Thats really not a lot if you get your spending around 30-50 hours a month on the game, your looking at $1 an hour of entertainment, max. I mean, I spend like $40 just going to a movie with my wife.
I guess it depends on your financial situation, but I wouldnt feel bad if I was in Kriss situation.
If you want to be surprised, look at my Magic Online expenses. This weekend I think I dropped around $150 on it in 2 days. Ive probably spent at least $5,000 on it since I started playing, too. -- "This thread has more subs than the actual game." Phantasee, in reference to SWTOR
