There is a tutorial on using an LCD that seems quite like the one you were describing. Don't try to start off making a big game like Pokemon. Learn about the LCD first see if you can make some cool patterns or animations and then go onto trying to make a game. However, start small. First try something like Pong, Pacman, Space Invaders, Tetris. Familiarise yourself with the game-making process. After that, if you feel you would know how to, try making a Pokemon-like game. If you get stuck, THEN you could come here and ask for help. This, however, is not a site where people will feed you the code mashed up so it is easier to eat and then put it on a spoon and say "Here comes the aeroplane". You need to learn to do it yourself.
