I have two ideas. The first is about the wardrobe.
We need to change the interface to make it easier to choose between clothes we have already bought. To do this I suggest splitting the current "wardrobe" into a Clothes Shop and the actual Wardrobe. We can have links between the two and the Shop can have a preview option similar to what it has now.
Subscribers should also get in-game bonuses. Not something like subscriber-only items (which could potentially lead to huge gaps in the game for free players), but things that make the game that little bit more enjoyable. Things like shortening the time it takes to do things, maybe knocking off something like a quarter of the time, a few extra inventory slots, a small bonus of currants at the start of each new day, and an instant get-out-of-hell button, could add more value to the subscriber option.
I would appreciate any input on the above ideas, especially the subscriber bonuses.
