I don't know whether I'm Hardcore or Casual and I wish I didn't have to think about it, or even that the distinction had to exist, but it does. I don't know why I even feel the need to preface what I am saying here with this but, again, there you go.
If I had to pigeonhole myself I would say I was Casual. I have a full-time job, a mortgage and a 2 year old son so there's a lot of responsibility right there, and little time for games. I do try and play as much as I can but that might only amount to 5 hours a week sometimes, and rarely (never!) am I able to commit to scheduled events or late night schtick. But if I was a purely casual player I wouldn't pour over combat logs nor would I be spending time on a blog.
There are people like me who can't easily be pigeon-holed, who might have limited playing time but want to make the most of it. That's why I like the reward system in Warhammer. It definitely keeps me playing.
Scenarios reward insignia despite losing and the new City system will also reward the losing side. Participation brings rewards but don't forget winning gives better rewards.
Rewarding particiption has rubbed some people up the wrong way but it shouldn't. Participation is required for a healthy and competitive game. Earning them shinines keeps people playing. If I felt I wasn't getting anything out of my precious 2 hour game slot then I'm sure I'd find myself drifting away, as well as many other players similar to me, and that would not be good, would it?
