Well, you asked for my contribution(through spam pms which are banned here BTW), here it is, in the form of a good old reality check.
First of all, your program of choice is ILLEGAL. Postality Knights is the cracked version of RPG Maker XP and is frowned upon in all good game-making circles. If you aren't dedicated enough to shell out $60, then you don't have the dedication to complete a good game, much less a POKEMON GAME.
Going on from this, do you not feel that you've posted this up a bit early? You have very few Pokemon concepts(don't worry I'll get to that soon), but more importantly you didn't even know which program you were going to use! I have a feeling you found JavaScript a bit hard and decided to turn to RPG Maker for its simplicity. Well you have a whole new thing coming because there is NO easy platform for Pokemon games and RPG Maker has never been good at handling that many scripts(you will need a script for nearly everything to make it Pokemon btw) and it gets very glitchy with complex scripts. (BTW do you know the Ruby language, or even better RGSS? Because you’ll need Ruby script to learn RGSS, which is the only language RPG Maker accepts.)
Just take a gander at the credits roll in Platinum sometime. Each person there put in a phenomenal amount of effort into their section, an amount so high that the only way to reach their level of dedication would be a money incentive. (In other words they were making the game to survive.) Now a money incentive is quite illegal with fan-games(well actually the whole thing’s illegal but Nintendo will actually care if it’s become profitable.) and besides that, I doubt you would have enough money to make it worth people’s while and make the whole thing worth your own while.
Don’t try and use Pokemon Acanthite as an argument, because Fangking Omega is an amazing co-ordinator and a jack-of-all-trades who also launched his fan game with a decent amount of information and something to separate it from the real games and indeed other fan games(its inclusion of an actual story). Despite the many contributions from a multitude of talented people, Pokemon Acanthite has not gotten as far as a demo. (I’m not saying they won’t, just that it’s taking a tremendous amount of effort.)
Then on to the content. You have NOTHING except a vague statement on some of the simpler decisions(the gym types) and some uninspiring Pokemon designs. (Sorry man, but quite a few of the Starter Pokemon(the highlights of the generation) are really just circles. =/)
I suggest you reconsider this all before pursuing it further. Maybe just take the thread down whilst you work out some details and get the ability to actually get it all working.
Cheers, Pokemaniac
P.S. Thank you for bringing me back to my days ripping down games on RMXP.org. I sincerely hope you reconsider. Think about it – maybe do something simpler than Pokemon. Start small and get competent at game making. Maybe when you’re older, looking for a job, you could pursue a career in game making. There’s a lot of money in the homebrew game making business(Aveyond comes to mind) so try and work up your skills for a commercial game.
