Pokemon should serve a function beyond simply battling. One of the major things illustrated in the show is that various pokemon can be used to solve various problems. Simple examples would be the use of Rock Smash to clear a path or surf to travel over water.
Also, since the pokemon world is very clearly huge a great Pokemon should also offer an alternative means of travel, assuming they are the right size. So instead of wasting money on the bike maybe you have a Rapidash and you ride that, or a charizard to fly you around. Of course to balance this against actually buying the bike, maybe a pokemon has a riding stamina so after awhile they need to be put back in their ball.
Another point to look at, that pertains to combat would be controlling the pokemon. I think that once a pokemon is brought out the player character assumes control of the pokemon, while their avatar follows. A pokemon should have two modes, combat and exploration. The combat mode limits the pokemons walking distance (sort of an invisible wall that keeps them close to their trainner) at this point the trainner stops moving allowing players to focus more on the battle and less on wondering into angry, wild pokemon. A side from a change in mobility combat and exploration mode could have a difference in use of a pokemons abilities. So while in combat mode rock throw plays out an animation of your pokemon picking up a rock that is not persistant to the world ( you don't need real rocks to be around to use the attack) the ground and throwing it, in exploration mode the pokemon picks up movable rocks in the world and places them where ever the player so chooses. This allows for problem solving on another level within the world itself and allows for some fairly creative puzzles.
Oh yeah, combat should require real player accuracy rather then relying on a stat. This allows for strategy as well as use of terrain in battle.

I'm sorry that i haven't been on in a while. About two months ago my mother passed away. She had been dealing with lung cancer for a while. It's been like a roller coaster for me the last five and a half years. I am angry,depressed and fustrated because my mothers not hear anymore. Iv'e been kinda out of it dealing with everything from arranging the funeral and all other sorts of things,but I'm dealing with. The last words That she told me was be strong and to take care of my little brothers and sister. So I'm doing what i have to do. I hardly had any time to write this or to be on my computer at all. I wanted to make the pre-beta list but I guess that's out of the question now. Hopefully I'll have a chance to play the game when it is up and running.

I just wanted to know will there be 2 on 2 or double battles with npc's or other players. Maybe there could be four players that can come together and battle 2 on 2. Just a thought someone please get back to me I would love to here input on this topic.

i think it would be cool just to make certain parts of your pokemon a different color. Such as a fist or arm of a pokemon could be red and the rest of it's body would be the original color.

The thing that can make this game better than the DS game is trading. In the GBA and DS game you can only trade pokemon with other people that have the same game on the same handheld. Trading on this game you should be able to trade buy just requesting trades with other users make it a very easy and simple thing to do. Also the should be a trade balancing system where users can make a three or more user trade.

This is good for some one like me who just started out
 thanx for the good news
