I liked the seasons in Unova, but would like them to only affect how the game looks and not what wild pokemon are or aren't available. I was never too big into Pokemon Contests, but they were fun to do once in a while. so I don't mind if they come back. Fog in D/P/Pt was awful. Fog should either have no affect on battle at all or be totally overhauled into a type of weather like rain or sun that can be used in battle. Trainer customization is great and I think should be included in remakes, perhaps after beating the champion. Sure R/S/E didn't have trainer customization, but OR/AS included pretty much every other major Gen 6 feature not present in the originals so I don't see why customization had to be excluded. Hopefully customization comes back in the future. I never used Secret Bases much, but I thought they were pretty cool. I'd like to see some feature similar to it in future games. I loved and used The Underground a lot. It is my favorite way of farming for items, especially evolutionary stones and fossils. Gym Leader rematches was one of my favorite features in Gen 3 and 4. I also like the Pokemon World Tournament in B/W2. Hopefully Gen has some way fo rematching the gym leaders. The Battle Frontier is one of my favorite postgame features ever, so I'd love to see it come back. Some features not mentioned I'd like to see are: I liked the different theme remixes for day and night in D/P/Pt for the routes and other places. It added to the ambiance Sinnoh had and I'd like to see it return. Another thing I'd like to see come back was the shaking grass/rippling water/dust clouds from Gen 5, hopefully with a lot less Audino. I liked being able to catch rare mons like Kingdra and Milotic without needed to trade.
