Help with PokemonDB! Changes between games.

Question

One of the (many!) things I am working on is a set of pages for each game. For each one I want to list some of the key changes and updates in each game. Something similar to the right hand column of http://pokemondb.net/black-white

For example in Diamond/Pearl, we would put that they changed the physical/special move categorisation to be for individual moves, not based on the move type. And in Ruby/Sapphire double battles were introduced.

Anyone who wants to help, simply post an answer with some of the changes. You can list as many or a few as you like. Try not to repeat what others said. Huge thanks in advance to anyone who helps!!

There was time and day system in RSE but not in FRLG

Yep, Shxatoap is right. The time/day system in RSE was barely used for anything though.
