I'm gratified to see the edit received well so far.
Interesting idea about the plasma, but I prefer to keep the crawl intentionally vague. If I mention something specific, I think it falls flat to never have it referenced or mentioned again in the narrative proper. However, I admit that it's pre-existence as an EU idea makes it a little more intriguing. At the end of the day, I think the crawl works better as it is than throwing ideas into it that aren't expounded upon in the film itself. "Abundant resources" steers clearer of this than "plasma resources" would.
