Is it ever the right time, market, fetishes, story setting, game mechanism, or whatever else ?
I'm sure that for your friend it wasn't the right time to buy his two caravans, and so, who care ?
Like you implied, for most thing, the right time is "now". Perhaps he could have waited one year more, and now own one more caravan for the same price. But it's "perhaps", and by buying when he did, for one year he had the income from those two caravans, right ? Not like the guy who wait since 19 years and have earned nothing yet. Hell, most house loans would be over 20 years... If he started the first year, he would get full benefit one year later. Saving the earnings, he would also be able to buy another house with a way shorter loan. But since he wait for the right moment, he have nothing...
The same apply when it come to game making, as long as you have the time for this, starts now, period.
Most games need two-three years before you complete them, so it's not the right time now, and so ? Who know if it will not become the
must have story setting during the game last year of development and, yours being near to its end and now relatively know, you'll catch all the attention and money.
And it don't limit to the story setting, it's also true for the quality of the writing/CGs. Starts now with something average, and when you'll starts your next game, with all the knowledge you now acquired, you'll be already known, and also trusted since you now have a finished game. If you were cautious with what you earned, you'll also be able to buy the top computer of the moment, what would already greatly improve the quality of your CGs if it's 3D renders.
Yazen_ at worse, if you don't feel confident enough with your capacities, starts with something else that your great story, keeping it for your second game, once you've improved in all fields.
