Am I correct in reading that both books in the set are only a mere 100 pages?
Either the rules are skinny or there little fluff in that case, right?
I recall 1st edition being very thin.
What was 2nd edition? About 200 pgs?
Nothing out of the norm. I suppose that since it doesn't include a magic system, extensive world-backgrounds, or other similar subjects included in many RPGs, T2000 is mostly down to mechanics and equipment.
They're also adding Solo Play rules now, more setting/scenario stuff, and a new stretch goal is up for adding 50% equipment. The page count is steadily going up.
