I don't think it would have made sense to condense the links (AFAICT they aren't very thematically connected) but I would say:

a) posting 5 things in a row feels spammy, I'd personally have waited at least a day in between them. I realize you're cross-posting from EA and they're already written but it's still good form to wait)

b) when posting a link post a good practice is to include a comment that explains some context for the link.
