I’m just trying to be helpful, because my game always seems to flop after every update.
I’m not sure I understand this. How is this related to you recommending other people’s games?
In other sites, including details in your game’s page about other games can be seen as trying to get popularity from successful projects, and is often not allowed. I’m not sure how this is applied on Itch.io and if there is a rule against it.
Personally, I would advise against it. If you want to help others, you can post games you recommend to others on Recommend a Game.
Edit: Just re-read the question, you should be able to include information of other games on your profile page without issues. This comment referred to including other games on another game page.
