That is NOT the correct reason to make a game for a hellishly large amount of reasons.
- Your game will most likely not be as popular as those other “popular” “open-world” games. Not because you’re better or worse, but because you’re going to be starting from scratch, while they aren’t.
- Do you like open-world games? If you don’t, you won’t make it to a finished game. Game development is one of THE most demanding and headache-filled arts in existence. I know from experience.
- By the time it takes to finish your game (YEARS), the gaming landscape will’ve changed, for better or worse. You can’t rely on a future that doesn’t exist.
What do you actually want to achieve out of game development? Because your mindset, from what I’ve seen, isn’t sustainable.
I haven’t said this in a while, but it still holds true:
Game development is a lifestyle. You can’t just work “here-and-there” and expect to make any meaningful progress or learn anything of value. You gotta commit a lot of time and forge a lot of social connections to make it work.
Also,
THE. WORK. NEVER. STOPS. EVER! Trust me.
