As of this announcement, PAX will be redone in that the game will be less complicated. The fear of players made be reconsider how the game should be. The goal here will be to make PAX less data-heavy and emphasize the focus on gameplay.
The following will be removed:
-Almost everything will be available from the start. "Almost" because some content may be unlockable, though I haven't decided on everything yet.
-The loading screen will be gone, or at least be faster. This will be good news to most of you who hate waiting. The purpose of the loading screen was to load data and data-related assets. With values for at least 1000 PC box slots and 600 bag item slots, it would lag a lot if it was all loaded immediately, forcing me to create a long loading screen. Now that most of those aren't needed however, expect less waiting.
-Removal of levels and exp. Every Pokemon will be as if they were level 100. Individual levels for each Pokemon obviously still requires massive data use, so removing leveling entirely would solve that. In the older versions of PAX, you may remember the single level stat that players had that increased even if the player doesn't do anything. That's not coming back either, of course. Instead, something similar to a ranking system will be created. More details about this will come in the future.
-With removals of features mentioned above, other things not mentioned will be removed/scrapped as a consequence: trading Pokemon, breeding, move tutors, anything involving evolution(not mega evolution though), and others that I can't name at the moment. These features weren't added/fully completed yet anyway, so not much is lost here, unless you were waiting for them with high hopes.
While features were removed, some will stay, such as: switching, exploration, missions/quests, certain shops, base building, items such as costumes, etc.
You can also still set up your team of Pokemon. The biggest difference between now and then will be that you can set up your Pokemon any way you like and save it as a "loadout" for future teambuilding use. Setting them up will be similar to how you set up Pokemon in the Pokemon battle simulator Pokemon Showdown. This will probably require some data use though. I'm not exactly sure how this will work out yet, but I'll keep thinking.
Since you'll have almost everything from the beginning, there won't be much incentive for fighting enemy Pokemon. To substitute sticker drops, costumes and other novelty items will drop instead. While they may use data and can disappear if a data wipe occurs, they aren't as key to the game as a whole box of hard-earned Pokemon would be.
In a way, PAX is sorta going back to its roots. The "rewarding" aspect of the game is lessened, but in turn gameplay would hopefully improve. Ideally, the game would become something you'd want to play because you want to have fun, like Super Smash Bros., rather than a game where you just want to grind for everything and be done with it.
If you have any ideas, concerns, or objections, post them here.
