If you folk want to join forces for this, I'm very happy to help.  We can combine our different experience and skills.  I like writing game engines, but not so good at game design, graphics, sound effects etc.

So if there are any good ideas and people prepared to contribute (ideas, testing, graphics, sounds as well as coding), then we can have a go.  A good game idea that is reasonably doable is the biggest challenge.
