If we really are headed into another 12 pages lap, there is actually one very straightforward paying system that I feel has fallen between the chairs in the 4 box system:

Payment (one-time or periodical) required to play, no rewards in game
(Possible additional text box info: Yearly subscription required, Free 1 month trial)

To me that is the fairest commercial system, although obviously not nearly as profitable to the owner as the pay-for-perks system, which I guess is why it is becoming increasingly rare.

I wouldn't hesitate to choose such a game myself, if I liked its other features. After all, I paid by the minute for the 'Free' Mud I played for years, while still being on dial-up. (Not to the game owners, but to the telephone company, but in praxis that distinction didn't really matter). Again - to some of us money in itself is not the issue.

On a side note, my original suggestion still stands:
Implement the 4-box system now, evaluate it in a year's time by checking how it is being used and the percentage of each search option being called for.
(Make the default choice A, in case no box is checked by the owner).
Meanwhile discuss possible improvements, and if necessary upgrade the system later.
