Old Sims 3 games

So I will just never be able to use/play MY purchased games from YEARS ago because I can't remember the login to a dead acc?? Even if I provided all owned game codes, why can't I just get the 1st letter of the email those codes were redeemed on? Like come on, we were kids then! I would love to play my games again on my new acc without having to purchase them all again. This has been an ongoing battle for folks for a while now. There should be another way!
