With the introduction of the MECHANICS_GENERATION system in the settings script, it has become much harder and more confusing to figure out what exactly is being set in each section of the settings script. The descriptions of each mechanic mention it being set as true or false, while the actual option will say for example MECHANICS_GENERATION >= 5. This is not a true or false setting, as there are many generations the mechanic could be set to, and figuring out how the mechanic works in each generation requires looking it up on Bulbapedia or some other Pokémon information site. Making it a simple true or false, following the description would be much more user friendly and would not require the use of external information sources that make the process take longer than it needs to. MECHANICS_GENERATION works fine for setting the generation style of your battle mechanics, though, as that one is pretty straightforward.
