Yeah, there's a resurgence going on; Warhammer is getting more popular too again, even with the youth. I want to like it, but I can't bring myself to shell out €50 for a starter kit which looks like some plastic figures and a cardboard box on the back (some assembly required).
Fairly cheap per hour. I think it realistic to be less than 25 cents per hour. I suppose it depends how much effort you put into detailing, and playing.
How much it is per hour depends entirely on how often you play it. A Warhammer army can easily cost hundreds of dollars, and over $1000 is not unheard of. It can be cheaper, but RPGs can be completely free and eat up as much or as little time as you want.
Though I suppose if you count the time spent painting the minis as time spent playing, it's likely to end up fairly cheap per hour.
