[RMMV] NEEDING HELP DECIDING FIRST GAME PROJECT

I'd personally go with whatever you feel you are most driven to create!

When it comes to first games, I'd generally start small, as you can get a feel for making a game and not have to stress as much with a long project, which could take years.

As for the fan game versus original, which one excites you more? If neither jump out to you, they both have advantages and disadvantages. Fan games have an audience already baked in, of course, and can get noticed and get popular quickly if they're well done, but there are also weirdos (like me >.> XD) who would rather play original works.

Start with the smallest idea since thatll give you a chance to learn the software without having to make something huge. Generally the better your skills get over time the bigger the projects you will be able to comfortably tackle.

That.
Just don't start with your favorite idea because you're very likely to have 100000 extra ideas while making the game and just drop your current project and start something new. Happens all the time.
But if you don't want to enter the start game -> get new ideas -> drop it and start another cycle, definitely go for something small and create the habit of finishing stuff, even knowing you could have done better or that you wanted to create something different.

I would start with a small idea, which is also a simple one and doesn't require many plug-ins. For example I wouldn't toy with custom battle systems or menus. You can learn that later. You can go for custom resources as they might make you more motivated to finish the project. It's likely that you'll learn a lot while working on it and on whether your ideas are actually good.
So, if there's an idea for a simple linear dungeon crawler or a narrative driven experience, go with that.
