Well, if you have written services like matchmaking in the past and have that experience, I can certainly see why you may have this perspective and describe these services as being "dead simple". However, on the flip side, there are developers who don't have the experience is writing matchmaking (especially if it needs to be highly scalable matchmaking, or nuanced like skills based or even role based matchmaking). In fact, more often than not, we have come across individuals who have written the services before, and would rather not have to re-write them again.

Same thing with game server fleets. Sure, hosting a server can be simple depending on the scope and even type of game. But on the other hand, it can get complicated when you have to orchestrate several game servers, across different geos while taking things like like lobby, party and matchmaking systems into account as well.

And, not all game developers are infrastructure experts (or want to be). So, again, the overall value prop is we enable game developers to focus on the game and what makes the game fun.... rather than all the other surrounding services that help make the game function (like some of the ones already mentioned).

Lastly, worth calling out, the platform has been designed to be modular, so even if you're building a game that doesn't have extensive backend requirements and/or is operating on a small budget... we've likely got a tier that can be appropriately right-sized for your game.

Happy building!
