Game progression was too easy for a whale IMHO. You'd get a girl, have her fully foxed out and evolved instantly (or as soon as her youkai mats were finally available and no amount of whaling would change when the youkai materials became available) and then you were pretty much finished except for that "Might as well be a 2nd job" guild wars thing that sucked out four hours+ of your life every friggin' day.

Once you were at that point, it's like, what else is there?

I would have stuck around anyways if Guild Wars didn't literally devour my life (or 4+ hours of it every day).
