I've been going over various flavors of D&D (original, classic, retro-clone, etc.) and I was just curious if there was a reason behind the "roll higher than AC to hit" rule in Microlite20. As far as I can tell every other form of D&D has the mechanic as "equal or higher than AC (or some target number in a table)" to hit.
I'm looking for something simple to introduce a young relative to RPGs and microlite20 seems to be the best thing I've found so far. I haven't played much since BECMI D&D and AD&D 2E, and I'm amazed my younger self absorbed all those rules.
