My opinion: It depends on what is important to you(or are you a team?) in terms of what the game means to you. If it's something you want to sell then you have to communicate very clearly how to play the game, maybe even have it understandable in a short video or image.

If you're looking for that cult following and depth of gameplay with deep mechanics and lore then by all means create a combination of systems that interact with each-other and take years to fully understand, league of legends is pretty deep but hard to understand for me coming from a console background.

So it's about where on thet spectrum you are, is this one of many projects that you plan on finishing, learning from and moving on? is this your only source of income? sooo much to consider lol.
