It does indeed have at its core the power mongering ridiculous Ability score bumps both at character creation and at levels 5 additional points during level gains.
Humans get +1 to all stats at the start and all characters appear to get +2 to a single Ability every 4 levels.
The maximum for an Ability score is capped at 20,what good is that when many of a character's Ability scores could get to 20. There may be some differences for the non-human races once I take the time to examine things further
The experience table is designed for very rapid level gain. The potential exists to go through 24 hours of play and have characters go from 1st level into the very high levels.
There may be more things I would change or eliminate from this Not-Basic, Basic game, but I won't know until I have time to read the entire thing a couple times through.
Mearls, you got some splainin' t'do . . .
