Personally I didn't mind R/S. But random weather all over the game would be heavenly. Imagine snow in Rustburo, rain in Fortree, a sandstorm in Lavaridge, sunny weather in Lilycove or fog over Route 118. And all you have to do is click on the television and get the daily weather report.
I agree. They should have this in the R/S/E remake and you should be able to get news from the Weather Institute. On a side note there should be a Pure Grass tournament in April.
