Ignoring your borderline-austistic understanding of social situations, there's a precedent for what's happening.

Virtual Boy was a "handheld"(?) console that absolutely bombed. No question there. It was also a fifth gen platform, and launched in 1995. Three years later, the Gameboy Color launched and quickly replaced it and the Gameboy/Pocket, yet remained part of Gen 5. Time frame plays a very important role in what generation a platform falls in, but "mulligans" relatively early in generational cycles have been shown to not move up to the next generation.

Handhelds doesnt have gens.

No they dont. Its just us counting them as a part of whatever console gen theyre released in.

Except yes, they do.

Super petty, I know, but

"I dont mean to be rude or anything, but is it really that hard to understand what a gen is?"

Ok. Give me the systems released in gen 3 of the handhelds then...

So your argument for handhelds not being part of console generations derives from no handhelds appearing in gen 3, despite handhelds existing in both gen 2 and 4?

No, you say handhelds have generations of their own. What systems are gen 2 then if thats easier?

No, I said they have generations. Those generations are shared with home consoles.

Game & Watch, Microvision, Select-a-Game, Adventure Vision, And Epoch Game Pocket.

Again thats just us gamers giving meaning to what era a handheld is active in. The Gameboy was a part of gen 3, 4 and 5 if we go by that.
