The 20 page version is the old 3.5 edition. the 172 (actually smaller than that because they fucked up the page numbering at some point) is the newer 4th edition. Trust me, even at 168-ish pages, the 4th edition should satisfy your rules-lite itch quite easily.
The core mechanic is that most rolls have a check target number (CTN) composed of one Attribute + one trait + various bonuses or penalties, and you need to roll equal or less that that on your d20 to succeed. However, here's the twist, you still want to roll closest to your CTN as your result will determine many things, such as the damage inflicted in an attack, the amount of HP healed with a healing spell, that amount of damage you avoid with a Defense roll, and so on...
There are a few other details, but this is pretty much like 80%+ of the rules right there...
