So I guess you're saying that generally, the more risks you take, the less likely it is to be as much of a commercial success as if you played it safe with entries in familiar franchises and formulas?
And do you want the big companies to essentially make more AAA 'inde games' (creative, original, etc) with high budgets?
It makes sense that familiarity tends to be the safest bests most of the time. But aside from looking at how much they sell compared to other games, repeating new entries in a franchise is also very important to get more eyes on the franchise and have it grow to where it could have been a long time ago.
Final Fantasy VII, Persona 5, Nier: Automata, Yakuza 0, Dragon Quest 11, Monster Hunter World, etc.
There are a lot of these games where one particular entry in the series does a much better job at attracting a wider audience than usual for whatever reason.
And then you have those newcomers try out older games in the series, and probably more often than not realize that this was something they would have liked all along, but didn't know it at the time.
I'd like to think that game developers tend to compromise between cash-cow safe bets, and projects that are expected to make less money.
And the former can fund the latter, so for that and many other reasons, we tend to see those much more often.
I remember Shuhei Yoshida said something about how they never expected The Last Guardian to sell a lot, but they made it because they knew the fans wanted it. I imagine those kind of passion projects are easier to pitch to the CEO's, or justify to investors when you have some safe bet games alongside them.
