Akira, both IFW and Galahad are telling it how it is. Basically don't make a clone as people will only play it for a couple of minutes (for the novelty) and probably will never look at it again. Keep it simple is good advice. I'll use the old cliche and say don't run before you can walk. This reminds me of that "EAB Game" thread. It shouldn't be too difficult to think of simple game ideas. How about something like an EAB sliding block game where you have to arrange the blocks to make a "picture" of an EAB members avatar. Something simple like that. If you set your sights to high then you will quickly become bored of the project as you realise it's far too much work. Keep it simple, keep it safe.
