This is just my opinion if you disagree state why so.
Reasons DPPt sucked:
1) The 4th Gen Pokemon are the most rush and uncreative
2) The Physical-Special split
3) The story line with Team Galactic and such was too over the top
4) The Gym Leaders and E4 were way too easy
5) The Sinnoh region doesn't have many Water routes
I think at this point, people will always find reason's to hate the newest generation. My opinion on DPPt at least is as follows.
1) As far as pokemon goes, I don't think it's fair to right off any pokemon as uncreative. Many pokemon are based off of animals so while people love to complain about pikachu "clones," Pidgey "clones," Caterpie "clones" etc. It only really makes sense, how many types of birds are their in the world? How many types of bugs? Marine life? It would be weird to head to Sinnoh and find a bunch of mythological, 8 headed beasts while Kanto, Johto and Hoenn are filled with relatively normal pokemon.
Though of course I also understand that pokemon in many cases doesn't make any sense but I think finding a balance between reality and fantasy has been a huge part of it's success. You can go catch plain, cute pokemon but at the same time you can go hunting for that magical dragon most people dreamed of as a kid.
Do I like every pokemon from 4th gen? Hell no. But I don't like every pokemon from the first 3 generations either.
I'll admit to be being dissapointed by the water pokemon this generation though. The animals of the sea come in all different shapes in sizes and the diversity was alittle dissapointing for me.
2) Thought it was about time and one of the greatest things to happen to pokemon, but that's frankly my own opinion.
3)Well yeah...but that's to be suspected with the nature of Dialga and Palkia. I've actually grown to love the conflict they bring to games and enjoyed the experience I gain from them. If anything I just wish they didn't all use the same 3 pokemon >.<
4)Really a matter of how you play the game. The gym leaders are easy for me cause I had 5 pokemon at level 50 before the 7th gym cause I spent hours training in Iron Island for no real reason. That was my own choice. I'd like for you to be able to choose the diffculty of your game before you start. So people like me can have to train their butts off to keep up to gym leaders while more casual players can play it as it's played now.
5) Mt. Coronet's grown a little tedious for me and getting slowed down on route 217 was annoying but every region's had it's surplus of things. I like each region for what it is, just cause I convince myself I'm exploring a new land. And in reality, you can't choose what the landscape looks like. I what have liked a little more water though too.
Random note. I loved Rock Climbing :P
Agh, D/P/Pt was the worst. xP The storyline was way too extended and also with that, all of the towns were extremely boring to be in. There was just no element that excited me about the game, (aka why I used an Action Replay so much). I'm so excited for HeartGold and SoulSilver, there's so much to do! (Two Regions :D)
The storyline was too extended but you're excited for HeartGold and SoulSilver because "there's so much to do!" ...Um what?
I agree with you on the towns though, they were failry dissapointing. I personally loved Hoenn in large part to the diversity in the towns. Fortree and Sootopolis were awesome :P
