Preface - I acknowledge that I am new to game development, and this will require a lot of time, effort, and dedication. I am willing to spend up to a couple years working on this every now and then in my spare time. I've thought this project over in my head a thousand times, and I've come here to seek advice to where to start. I have a basic understanding of computer programming from taking some courses in high school (pascal and C++), and I understand variables and all that jazz.
What I want to make:
Massive crossover of all of my beloved characters from the SNES era, and sprites permitting, a few other famous game characters. I'm talking 50+ playable characters.
Very long game with a very wide array of graphics, music and sounds.
I believe this is feasible in RPGmaker XP/VX with enough dedication and by finding a way to have one save file work for multiple games.
What I want to know is if a project of this magnitude is better on XP or VX... or if I should seriously look away from RPGmaker. I currently want to use RPGmaker for its ease of use and to not have to code my own battle system by hand.
Anyways, let me know what you think would work best, and thanks in advance!
