>>19917304For poison I think that they got rid of it because it was kind of pointless to begin with, seeing as burns don't hurt you out of battle, but poison does? Rather then change it to have burns do that to I guess it was easier to get rid of poison actually doing damage. Not like it made things harder unless you were under extreme circumstances (like if you had no healing items and one Pokemon left that was poisoned and about to faint, this happened to me in FireRed)
>>19917431I heard it was not because of the battles but because of them getting confused on where to go. That's bullshit, Japanese kids for the most part had no trouble getting through the previous games which arguably had places that kids would have a harder time getting through, yet Platinum? Really? It's not like it was even a surprise, Diamond and Pearl had came out already.
Even then, to make the region easier you don't need to make it linear like they did, just add an NPC that says "Hey mang, you should go here." The games tell you where to go anyway, no need to make the region only have one path to go on top of that.
