In my opinion a good point and click game needs to meet certain criteria. It needs random and witty characters who you probably wouldn't talk to in real life and lots of things to look at. It must also be drawn in a rather glossy cartoon fashion, and the main character should have a really stupid name.
Runaway: The Dream of the Turtle seems to be pushing most of these buttons so far. It is an upcoming point and click from Pendulo Studios, due to be released in early March. It is a sequel but the first one was pretty hard to get your hands on in the UK. However when it is mentioned to those who have played it, their little faces light up in joy, which is always a good sign.
