Probably a mix between classic & hardcore.
I can play for really long stretches at a time, and I usually only dedicate my gaming time to one or two games at a time.

But I'm not really quite as good as some of the harder-core people out there though. Not even close. (e.g. I don't have a great interest in playing the market/crafting, so I won't have the resources for penta-melds, for example. Also, I don't have every class levelled up, nor do I dabble in things like the sightseeing log.)
