Looks nice! I just wanted to mention this part:
If you need to update the Post with something then You can post another one, all old posts with the same game will be deleted
Is there any sort of validation for this? It could be a source of trolling, if someone wanted to sabotage by making a fake post :)
Also, for some reason the Terms of Use button on the add game page doesn't work properly, it just sends you to the main page instead. I'm not sure why since the link appears to be exactly the same as the About button on the main page.
