What projects have you already completed? You can use your own history to measure how long it might take you to make similar games based on your own skill and ability along side your current experience. What someone else can do has no baring on what you can currently do today… All it means is reaching that goal is possible with the right skills, experience, and money (unless you don't need paid tools, assets, or people - severs are also not free for a MOBA)… This will determine your time as well but you'll have to measure it based on your own history. If you've never done anything before then I would forget about it for now because it would be nothing more than a pipe dream at this stage.

Game development goes beyond just code. Those who take on several disciplines at once (Art, programming, design, writing, sfx, music, ect…) have to devote many years to the craft. Expect to devote several years per discipline if you want to gain competency. Some of the individuals on here showing their games have been doing this for well over 5+ years, and even some much longer.

Typing lines of code is not the problem. The problem is knowing what to type.
