That's kind of a bad comparison...you're continually paying Adobe for (generally) one program that you're going to use every day for years. It would actually make sense to just pay a lump sum upfront and then again maybe a few years later for a newer version.

With Gamepass, you're paying for access to many games, each of which you're going to play for a relatively short time before moving on to another game. If you spend a lot of time gaming and enjoy novelty, it makes a lot of sense.
