This happened to me a few times lately.
Half Life 2 VR Mod - Played it for ~4 hours, before all of a sudden it won't launch. I click on play in Steam, and after 3-4 seconds, nothing happens, then the play button is active again. No errormessage, nothing.
Resident Evil 2 Remake - I have almost 15 hours in it, almost finished the Claire campaign, when from one day to the next it won't launch. Just a black window pops up for one second, then it just stops, the play button is active again, so this game also leaves the user hanging without any errormessage.
Look, I have been gaming on PC since 2000, and with 25 years of experience, these situations are infuriating for me. I have my goto steps (check file integrity in Steam, update nVidia drivers, ec.) and if those don't work, I look on the Steam forums, google, etc for solutions, so eventually I'm gonna figure it out.
But dear gamedevs, please, please, please for the sake of less savvy players, include at least some clue of what the user should do. A blanket statement to the effect of "game failed to launch, please try the following: verify game files, uninstall then reinstall game, make sure you are on the latest drivers for your GPU, etc etc. If game still won't launch, visit our FAQ page here, where we listed all possible solutions..." could suffice for people who just want to play. At least they would not be totally stumped, and would have some options before they also google the problem, but man... Also, maintaining a FAQ about launch issues, bugs, crashes, etc. would be expected for a paid customer to have support for their product...
I somewhat understand that in 2025, game devs can expect everyone to eventually google what they don't know, but an errormessage would still go a long way in establishing a communication with the user in the time of crisis - "Hey, we failed now, but we have some general ide about the problem, here are some general options, and here is where you could seek further help" is an essential part of customers support - even in 2025, and it's so basic, I don't even understand why I am still talking about this.
TL;DR - User loses it over games that don't show errormessages after failing to launch.
Games actually provide lots of debugging information, but not in an easily accessible manner. It is usually printed to
stdoutorstderr, which is to say, to a terminal output, and you'll only see it if the game executable is launched from a terminal or the outputs are redirected to a file.Yes, for you and me, this is useful information. But here is where I think, for less savvy users, even a blanket error would be really helpful, focusing on next steps the user can try.
