I really, really wouldn't worry about that. There's a reason Game Freak is making the distinction between these two games, and why they're constantly reassuring Gen 8 is for the older fans. The way I see it, LG is gonna function as GF making a Pokemon geared towards small children, while the new main Pokemon Gens will be going for the market the have always gone for: Primarily children, yes, but with plenty of stuff for older players.
I think we all need to wait for Gen 8 to show itself before worrying it's gonna crash and burn. I really think it's gonna turn out awesome.
EDIT: Honestly, though, we've all been derailing the thread a TON, and I apologize to the mods and other users for that. If people wish to continue this, let's move over to a Pokemon thread.
