Im thinkin it will be out the end of the year.
*bursts out laughing*
Sprites-> Original NES Zelda - Reason: Simple, so increases chance of project being stared...I mean finished...
Now my vote is aside: Don't do this. Not to be negative (well, yeah, to be negative), you
WILL fail. Simply how you made this topic shows that.
A game which has a chance of succeeding has a certain 'air' to the first public mentioning of it, a kind of 'charism' and 'showmanship' that tells us it's great. It's hard to say what makes these 'success' topics great, but their is something. A short list would be: Screenshots which impressive, possibly a Demo which shows the engine is damn close/has reached completion, a trailer if included is very well put together, though their are many more things.
Because you posted before, let's be fair, you had any content to show us, it instantly proves you are Impatient.
Why? Because you couldn't wait until you actually had something before you posted, therefore you lack the patience needed to make a full-blown game of this size, it will be ditched as soon as your patience runs out. That simple.
In short, even if this concept could work, which from what I've heard it simply couldn't, you lack the restraints and skills needed to complete it. You expect too much, if you were to attempt this it would not be finished by "the end of the year", or the end of the next year for that matter. 3 years of work at least before this would be anywhere NEAR finished, could you do that? No, as you have demonstrated you lack the patience.
Wow, that turned really negative and condecending, really fast, but sorry but it HAS to be said.
