Why every mainline Pokemon game is so fucking rushed? They have resources to put money into more people, or just put more time with having more money.

X/Y was rushed as hell. OR/AS seemed rushed too, not so much but it felt like it at times. S/M was rushed too with trials being implemented at the end and other stuff. U S/M wasn't rushed per se but had very little new content, so it could be rushed in a different way.

They have so lucrative franchise in their hands and they handle it in such a bad manner. How many fucking games are going to be rushed again?
