To be honest, I actually liked the side-quests. In my opinion, they have a lot more interesting appeal and fun in them rather than just the boring old cliche go-to-town-after-TOWN, defeating-gym-leaders, get-their-badges and whatnot. The side quests make the game more realistic and shows that gym leaders don't just sit with their fat a$$es enclosed in their gym waiting for some challenger to come so they could flop their balls about. It somehow reminds me a little bit of Megaman battle network 5 which is really fun imo.

Another element I liked in the game was the trades. You could have low levels of completely evolved forms of pokemon that could evolve only by trading (except of course, machamp). Thus, you could EV train your pokemon from completely low levels, which is nice in a way. Would've been more nice if there was a battle frontier to put them to their use though

. Graphics are amazing too. Not what you see everyday in a pokemon game

.
But I have to agree with you though, that light platinum does seem overrated. Here are a few issues I really found distasteful:
1. The fact that the creator had to use "Ash Ketchum"

.. Come on, why include "Ash Ketchum"'s name in a pokemon game? That name itself, only rightfully belongs to the manga. Ash Ketchup is got to be the most cliched name in the history of pokemon itself. And in a pokemon game, that itself, makes the game uncreative.
2. The fact that almost every single character in every city have the same scr
ipted speeches. Why not make all of them different somehow? That itself, makes the game so repetitive, that it's mediocre and completely harms whatever creativity the creator applied to it. - If you're going to implement something so repetitive like that in a game, why not make your characters identical? - *sarcasm off*
3. The hint guy in every gym.. Even after you win, he somehow doesn't congratulate you. Instead, the guy is unfortunately stuck in a time paradox and still goes on about what type you should use to defeat the said gym leader. The guy's fate just depresses me.
4. The rivals.. Not complaining about the too many rivals because that's pretty much an ok thing imo. But like the guy above me said, they have no personalities whasoever. Like Silver, for example. In Pokemon Gold/Silver/Crystal, he's basically the jerk-off kid who just had his period and goes ranting about how he's going to be no. 1, but always fails. While that personality gives it a nice feel to the original games itself, unfortunately you don't get to see that here. Instead, he turns... NICE?!?! So he basically shares the same personality trait as all the other rivals you're facing. It's like.. you're facing against twins, ffs.
5. The difficulty is also refreshing in the game. Unfortunately, it only gets difficult in the beginning. As you progress more, the game becomes considerably easier, and here's the irony: The game says "Lauren" elite four is more difficult than the Zhery one, but when I faced the elite four in Lauren, it's actually much easier than the Zhery one. Here's more irony: The world championships are much easier too.. I was able to beat Ash Ketchum with pokemon in their lv 70's -.-" .
6. There's not much pokemon in this game. Yes, it's ironic as it is. This game is said to include all pokemon from "Gen 1 to Gen V", but the problem is.. It includes only "a little bit of everything". I've completed the pokedex, completed the trades, completed basically everything.. But I still yet to see pokemon like ditto and rattata around, if there's any pokemon like that at all in the game. :/ Not sure if it's due to the limit in hacking the game (I'm not a hacker, soo I'm pretty much ignorant with this stuff) or something that's completely overlooked by the creator.
7. The fact that you basically receive mostly uber pre-evolved pokemon in every city from the start, like larvitar and dratini for instance. This completely reduces the challenge aspect of the game and makes it considerably easier to beat. Indeed, some people may argue that it "balances the game". But imo, that's not balance. Why? Because it makes the game so disappointingly easily later on that there's no point in even continuing the long playthrough. I only hope this was just a beta for the real release, otherwise.. No, just no. Thus, for the sake of satisfying my thirst for challenges, I had to avoid them.
8. Basically everything else that's been said on this thread.
The only thing I can say about this game is that.. It's Ironic.
EDIT: Almost forgot one more thing; the fact that you cannot fly to some of the cities in the lauren map is just annoying.. Okay, rant over. I'm done.
EDIT2: Well, sh*t. I seem to have too many complaints about this game o.O .. Another thing I find annoying, is that before you enter most of the gyms, there is no indication of what you should after that, if there's something you should do at all. For instance, how am I going to know which area I should explore to look for the gym leader in that particular town? Or that I should look for yet ANOTHER rival to fight with inside the bloody Drakebreath market before heading to the Elite four? Ffs, I wasted so much time having to catch a goldeen and train it to learn "waterfall" naturally, as I couldn't find the HM for waterfall and in the end, ANOTHER rival blocks my way to the cave leading to the elite four and says "I have to battle someone"

.. Doesn't tell me the exact place, so I have to waste time yet again, trying to snoop out this "rival" that's supposed to be fighting me.. Gosh, there should be some clear indication. Jesus Christ.
Take pokemon crystal for instance:
- when you enter Jasmine's gym, the hint guy says she's at the lighthouse.. Even the rival says it too. Thus, it's been mentioned twice where we should go, in any case we've missed that once..
- After you beat the ice gym, Prof. Elm calls you after you exit mahogany gym and tells you that team rocket infiltrated the radio tower. Thus, acting as a guide to the storyline diversion itself.
That's the indication I should expect with a finished hacked game such as this. How am I supposed to know what sequence I'm supposed to follow unless there's a CLEAR indication? Okay.. Rant over, NOW I'm done. *takes deep breath and walks away*.
