Hi Retsym,
One additional thing I think would be nice to include in the next game is the POV mode that you had for POVMan in Atomiquest, however, POV would be from Daniels point of view, and this would of course affect the POV camera angle.
As a second thing, I had an idea to pitch to you to put into that large bag of already nice ideas: a slice of life in a school dance / prom setting similar to HouseWife in that the game would have two parts but with a more story driven approach of The Goodtown Mystery. The first part of the game would be the days leading to the dance and the second part of the game would be e.g. the day before, the day of and the day after the dance. In the first part the objective would be to make a plan, get the interest to go to the dance, and do preparation stuff (eg. hotel bookings etc.) and in the second part the player executes / observes the outcome.
Replayability could be introduced by persisting some "stimulations" or "knowledge" between the plays which unlock new approaches or even new characters. So for example, perhaps in the second part of the first playthrough the player observes that some character is lonely or jealous of players attention to someone else. This would then unlock new interactions with that character during the subsequent playthroughs.
k, thats my 2-cents : )
Ta!
