I'm reading up on the cut gender differences introduced in Gen 4 on TCRF, and I got a question: How long did these last for? I barely remember them in Gen 4, but I don't remember if they stuck with them for Gen 5, seems like a lot of work for nothing. I very much doubt that these carried over into Gen 6 and onwards with the 3D models, with how little of a shit about general quality Gamefreak gave at that point.
Speaking of gender differences, it looks like Gamefreak wanted to go a step further and give females a different sprite pose than males, from the looks of it. Would have been even more work if they had to do two poses for every single fucking Pokemon, not to mention tiny differences between one another they had to adhere to for the rest of time.
Honestly, the only one that stuck with me was lipstick for female Wobuffets, since I used those a lot in my XG/Revelations Emerald playthrus. Threw me off at first that it wasn't present in either GC or GBA games.
