EDIT: Sorry if this is the wrong place to ask, but I'm not sure where else to ask this question

I uploaded a game to itch. I didn't create this game, nor have I ever claimed to; I do, however, have the license to distribute it. I am not a close friend of any of its developers, though we have communicated in the past.

In this case, would I post about this game to the "Recommend a game" forum or the "Release Announcements" forum? If I don't own the game and am simply giving it exposure/publishing it elsewhere legally, does it count as self-promotion to talk about it in "Recommend a game?"

I wonder if it would be better if I just posted on one of those forums and saw what happened.

Many open-source licenses permit free redistribution.  Some require attribution and others don't even have that requirement.

Whether they require it or not, linking to the original project AND original project's license on the main game page is a good idea :)

Keep the FOSS alive <3
