I've just finished playing the loveliest little 'point and click' Flash game called Samarost (look under 'Flash Games'). Actually, there is a Samarost, and Samarost 2. The first game is free (play online or check out the source code to download the relevant .swf files to play off your hard disk). The sequel has two parts - Chapter 1 which is similarly free, and Chapter 2, which is only available if you pay $6.95 (US) IIRC to download the “full version”. You can play through both games in a matter of hours so you don't get a whole lot for your money, but the graphics are well done and sweet and it's just a charming experience.
As an aside, I have begun using this kind of interactive short clip in some church services, asking the congregation to vote on what to do next. I used one a fortnight ago put out by World Vision Australia - Who wants to be the Treasurer? There's also another one particularly relevant to Australia entitled, Our Neighbour's Children.
