Lol, first of all I'm on the side of people who are AGAINST wiping the entire game and starting over with a fresh start. I also don't think there's an issue with the pokeconomy, people are either being greedy, or less greedy. Creo is right, the issue is that Pokemon are either in wide circulation, people don't want them, OR people are just more willing to catch them on their own then they were before.
Why should I buy your Pokemon, when I can catch my own Pokemon? What do you have, that I need, that you want me to buy? Unless that Pokemon is UC, or Token Store, the answer is 'nothing'. I think its that more newcomers are willing to be self made pokemon hunters. Rather than just money gathering and buying the first thing they see. They've become thrifty, and money conscious. Also, and not pertaining to S Pokemon, people have maybe become better at hunting what they want.
Personally, most people are perfectly happy to hunt their own HR's, S's, more than happy to buy their own Token/UC Pokemon. The kind of pokemon people are willing to spend money on now adays, have to be pokemon that it's near impossible to get on your own, or the kind that take the sort of luck only gods have (Drools over S salas). Wiping the system wont change that. If anything it'll make it worse. You wipe it, and the first person to catch a terrible Rat (a normal one) will sell it for 100m. Just because they can, and because no one else has it yet. Except that no one would be able to buy it..or buy anything..Except for people with money for tokens.
Still, I say we not waste years of progress, and not whine over dropping prices. The money will flow as it does, and peoples wants will change as they will. Just because you cant sell your thing for overpriced prices, doesn't mean others should suffer for it. This is Pokemon not Poke-millionaires.
Also, since were on the topic of Pokemon in new regions. Four points:
Point 1: Kanto and Johto are two different regions, and yet players can bring their Pokemon across them. Almost no one has a lvl 99 Pokemon after the first 8 bdgs (unless you solely lvld 1 or two poke on your team.)
Point 2: None of this stops newbies from obtaining higher lvl gym battling Pokemon once they can trade. If I want to give my friend a 99 Pokemon after they get the first 4 or 5 bdgs, I can. They can even buy em, and since gym battling Pokemon can be terrible, but also high lvl'd, its a common occurrence.
Point 3: If you've run out of Pokemon to lvl by time you reach Hoenn. I mean..if you've gone and leveled every single Pokemon in the Pokedex to 99.. Your either a bot, or you have more free time then any human should reasonably have!(Or your staff, you cheating robot overlords!) Most people create more than one team, and lvl more than just their first 6 Pokemon to 99. I know that I'm on 15+ myself, and I've made it a goal to lvl as many Pokemon to 99 as I can. The whole Dex if I can! Why do you think daycares are so popular? Cause ppl never have anything new to lvl..Nope, nothing at all.
Point 4: If I really want a completely new, fresh, beautiful, shiny brand spanking new beginning! I'll create a new account for the region. Cause that's what it sounds like your suggesting. If you want the 'experience' of new, make a new account. Everyone can do it, heck they can have more than one even! To make it a requirement though? Nah, that doesn't seem right. Cause you'd have to do it for Kanto and Johto as well, to keep things fair.
Personally. I don't think people would waste the experience points they could gain via gyms, by using lvl 99 pokes on em. That's pouring water into the ocean. Breathing into the air! Selling ice to an Eskimo! Most people aren't ....unsmart...enough to waste 99 Pokemon on gym battles. Especially since those first few gyms will be low lvl, and even a 90+ Pokemon wouldn't gain anything worth while from it.
It's the reason people start avoiding npcs after certain lvls. There's no gain, and no hunting chances. Though thats just my own personal opinion. No one need share it! Lol.
