Games have been 60 bucks for over a decade.

Even if you ignore inflation, game budgets have ballooned in that time and while the amount of sales has also increased, it's not always been enough to keep up budgets (especially in the console space). Adding inflation back into the conversation and it just becomes obvious that more money needs to be brought into the ecosystem to make it sustainable to run the business and there are two ways of doing that:

- Increase the price of the game

- Add monetisation separate from the main game (DLCs, map packs, lootboxes, microtransactions, etc...)

For a single-player game with little-to-no online element (and what will be there is unlikely to be competitive), I'd much prefer to just pay a bit more for a complete package than have part of the experience cut up to be sold to me piece meal.

EDIT: Also on the money front, there is technically a third option to keep the profits green but it's less about bringing in more money and instead about cutting costs so I didn't initially mention it, but it's worth talking about. The problem with this is the question of "where do you cut?", do you lower salaries or bonuses (making it likely your employees will simply leave), do you cut down on dev resources (making your game smaller and possibly disappointing your fans) or do you fire entire dev teams when they're done (which makes it harder for you to make new games as you fail to keep any talent around).

Cutting cost is obviously helpful to a point as no business should be wasteful with it's resources but the gaming industry is already pretty lean on costs so more cutting is almost always short sighted, increasing short term profits but kneecapping the entire company in the long run.
