We definitely have some great resources thanks to TGsoGood and our other contributors, and people are still working towards figuring things out, so there are some great starting points for others who want to tinker with the game. I'd certainly encourage everyone to check them out.
I can personally attest to resources getting ignored over the years. I used to get emails or PM's from people who claimed to have "searched everywhere" for information that was readily available and clearly linked. While we were hosted by Gamespy (and again, screw Gamespy), we had to use Fileplanet for file hosting; it was a bit fiddly and none of us liked it, but it was part of the hosting agreement. The situation and how everything worked was explained in the very first question of the Downloads FAQ we had, which was prominently linked on the main page. Still, people "searched everywhere" for it, and claimed they couldn't find it. If linked directly to it, they'd have "read the whole thing and couldn't find the answer", even though the explanation of how Fileplanet worked was the very first piece of information in the FAQ. Some people want to be spoon fed, or if they don't immediately grasp a tutorial, have a new tutorial created just for them, rather than asking specific questions about places they're stuck, or keep working on it.
On top of higher than basic computer skills, modding also takes intuition and persistence. I used to just make rosters for NBA Live on PC, but as fewer people made art updates, I gave them a try and found out that I could make some of them. There are some things I've never been able to get a handle on, but I was able to figure other things out using the resources, and trial and error. Not everyone is willing to do that.
In all fairness, not everyone has the proficiency with computers or skill and patience to create mods, so it's understandable that they'd rather leave it to people with a greater aptitude for it. It's also more difficult/cumbersome than it used to be with NBA Live back in the day, which probably turns some people off. The
1% rule is also in effect, I'd say. Still, we do have those great resources, so it'd be great to see more people trying their hand at it. Even if you're not making a lot of stuff that you're releasing publicly, it's handy to be able to mess around with your own game for your own enjoyment.
Encouraging people to do that is easier said than done, but it's obviously worth pointing people in the direction of those resources. I'd also encourage new modders to ask specific questions when they're stuck (i.e. "I'm not getting this particular step, can you clarify/further explain [whatever]?"), and not be afraid of trial and error. Make backups, and you can mess around all you like.
