>>37819180LGPE is mostly in mainline style with removed features and mechaics. It's not a spin-off game by that definition.
At the same time it doesn't fit the rigorous mold required for a mainline pokemon game, as it has no continuity and no practically full feature translation.
Therefore a new term is needed:
LGPE are now 'sideline' games. This is as accurate as a single word description can get.
You can now stop this stupid flamewar.
