I miss the whole mining thing, now it's much harder to get these things in White, and if you have black you have to BUY THEM. I miss the Pokewatch as well, it was pretty cool and all, you had your Calculator and Peodmeter right there and a whole bunch of other cool stuff. I also miss how when R/S/E came out there was a double battle everywhere, and it was cool. But now running into a double battle is as rare as a Shiny. They have 2 in the whole game, 3 if you position yourself right before entering the E4 area. I also hate how they brought in 2 different ways to battle and you only do them once or twice. But I digress...
I'd hate if they took out Dive again, Dive is so much fun, replacing it with other in D/P/Plat. was the worst thing ever. I remember Dive from R/S/E and how much fun was it to look for the 8th Gym City? I'd also hate if they took out Nicknaming your rival. I mean for the next new game I hope they add it in again cause it's fun that you can name him something stupid, or whatever but it kind of makes you feel closer to him in a way, LOL
