I'm a subscriber, and also a "Poly is a waste of ink" person. Those mini-games are absolutely useless, and I'd never spend my (very valuable) time playing a one-off of Josie & the Pussycats. Gack.
However, if Poly can start loading itself with more maps (*lots* more maps) of anything and everything (modern, sci-fi, fantasy, or otherwise) I'll begin to warm up to it. The map of the bank, for example, was great. I'd like to see floorplans of banks, office buildings, space stations, space colonies, aircraft carriers, submarines, battleships, etc. (I don't play d20 Modern or Star Wars, but maps can be adapted to any set of rules, obviously. As well, maps are tough and time-consuming to make - which makes them even more valuable.)
As to the subscription bonus - fantastic idea. With the new format change, I'd probably not subscribe to it (instead buying the Dungeon-heavy issues once every two months). The subscriber bonus adventure keeps me subscribing.
