I don’t know a single investor that would not like a game studio that said “we have a massive back catalog of IP that is raking in cash with nearly no additional development or maintenance cost. We’ll try to keep making new games to keep the IP fresh and see if we hit it big again, but in the meantime, enjoy the money printing machine back catalog”.
It’s basically what Disney does at this point.
And, for that matter, record/music labels. Most records labels lose money on the majority of new artists they sign. It’s the 1-in-10 that break even and 1-1000 that go big and the 1-in-10,000 that fill out huge back catalog they just keep milking.
If only old games were as easy to maintain across every conceivable platform like movies and music are.
You are assuming old IP rake in cash, but I assume that the initial purchase is the major revenue along with any DLC. That is the usual model for older games. Live action games rake in continuous cash via micro-transactions and seasonal passes but not any retro games. All the time spent playing retro games is the time they could’ve been playing modern games with micro transactions, is what some publishers reason I reckon.
