I agree with the "don't give up too easy" part, Ezcool Gaming has been developing our project for a good year soon (10 months now) and we are only halfway through so far, but knowing that people are willing to help, listen to their ideas and conclusions, even constructive critism, is something that is really reliable in this branche, we can't "just" modify the game to what our heads wish, we really have to think it through before a project like this runs through, ezcool is 14 people, that took us 10 months to gather a decent set of people. We also wanted alot of classes and races and even new doodads when we first started, but now we decided to let that way untill we got our first part of this era out, so atm we're stuck with custom bushes & flowers since it is just a particle compared to the time and effort that everything else takes.
So yeah. Before you give up again or feel like you found a dead end. Take my advice trash it or use it:
Sit down and write every head goal you got, pick 6 of them that you want the most.
Then start one by one and brainstorm them, google the possibilities for them to actually be possible within the client, remember that this is a game MOD, not a new game. Not everything is possible. then trash ideas that are basicly impossible, no need to promise yourself or others something that is impossible, it will bite your butt in the end.
Then show the list to a website you know is full of experienced people to give their point of view on your ideas, to tell you if it's good or bad, if new classes is even needed within the game! and THEN you start recruiting, preferably recruite more than you need so you can choose who you think you need for your project, when you got all your people set, start working on the project, make sure it all goes by the plan you've written. Which is more important than anything else, we experienced that in ezcool when we didn't make a plan over our continent untill SirFranc asked if he could do it for us so we basicly lost 2 months of stupid world building because we didn't have a plan of it. So yeah, planning planning planning. More important than bling.
And last: If you got a big fond behind you, try and get a scripter to fix problems that you might meet when you progress through your project, we got a few nogg-it crashes fixed in ezcool to stop our world builders (including me) from nerdraging twenty-four-seven
So it's worth it.
and even more last, You can use this kind of projects for educational purpose, so take that chance and go for it !
Atleast I certainly hope ezcool is finishing this off so I can sit back and play through the world I made knowing that I can just relax after 1-1½ years of intense wow modding
