Point and click engine?

The engine itself is pretty straightforward and requires some basic things: -Defining a walkable area -Defining objects and their properties, such as obtainable, triggers, map links, etc. -Really simple pathfinding -An inventory (if it has that kind of thing) -Dialog boxes (I can't think of a point and click game that doesn't have dialog) -Room transitions (not so hard) And then if you want to get more complex, you can do stuff like making a way to define a mapping for combining items, timed events, etc. Even though the engine is probably simple, a LOT of time would have to be sunk into designing the environment, setting up all the puzzles and items, and writing all the dialog. Some games are difficult in a technical aspect, but in this case the difficulty comes from the "artistic" side. Uhhh but that's not the answer you wanted lol. No, I don't think anybody has made an "engine" for that yet.
