....omg Hamtaro. ;______; That was my childhood and you are really, really lucky to get that name! I'm shocked it wasn't taken yet! Welcome to the forum!
Well, Game Development will definitely be the place for you if you're looking to make a game with programs like RMXP and RPG Maker. Fangames are a very big thing on the forum and many members join to get involved in that; you'll definitely find others that can aide you in your journey. :) I can't point you in the direction of a specific guide though, since I'm not a gamemaker myself, but you will find helpful things for sure here. There's a
Resources and
Scripts & Tutorials subforum that you can use for some useful things to help you along. You always have the option of asking some of the regulars there as well, though they're likely a bit busy. There's even a nifty
Team Recruitment thread for people who are looking to get a team together for their project; be sure to check that out! I'm sure you'll get far if you don't give up since this really is one of the best places to create a fangame. People that give up are the ones that don't get anywhere at all, right? The struggle is certainly worth it.
Hope you'll consider exploring PC outside of Game Development, though, as there's so, so much to do here. You can discuss your favorite Pokemon games, chat about video games and music, discuss news, play trivia, participate in events, trade, battle, and so many other things. Let us know if you've been having fun here so far and if we can do anything to help! I'll try and dig around for tutorials for you but I can't make any guarantees, I'm not the best scout for these types of things. :( Perhaps you can ask the Game Development moderator,
Maruno, if he'd provide you with some links (assuming he isn't busy).
Have a nice stay on the forum, Hamtaro! Don't ever quit before then your great username would go to waste!
