i'm looking for any good romance/reincarnation/fantasy-ish light novel, hopefully with the mc getting stronger, or using his previous life's strengths/information so that he isn't completely a worthless person, harem is perfectly fine, but not absolutely required. i'm hoping for one that has been going on for a long-ish time, or even completely translated. i've read
Gunota ga Mahou Sekai ni Tensei Shitara, Gendai Heiki de Guntai Harem o Tsukucchaimashita!?
World Teacher - Isekaishiki Kyouiku Agent (novel)
Shinka no Mi (Novel)
And basically everything from Re:translations and Japtem.

And i thank you in advance for your help finding something.

hi.. I totally recommended this one http://https://www.mangaupdates.com/series.html?id=118176
you could access it for free on http://www.princerevolution.org even though it's not complete, but the translation handling this series was so organized, that way at least we got 1 chapter every month. They have been translated 3 series until complete (as far as I know)
It has comedy, family, and fantasy setting

Completed novels to check out:
Mushoku Tensei (Novel)
Tate no Yuusha no Nariagari (Novel)

Incomplete or ongoing:
[m] Douluo Dalu (Novel) [/m]
Yuusha Party no Kawaii Ko ga Ita no de, Kokuhaku Shite. (Novel)
Slime Tensei Monogatari (Novel)
Kenja no Deshi wo Nanoru Kenja (Novel)
Yomigaeri no Maou (Novel)
Kenja no Mago (Novel)
Zhaohuan Wansui (Novel)
Konjiki no Moji Tsukai (Novel)
etc....

If you like Yu Wo style definitely check NhanaT's suggestion.

thanks for the good idea's on what to read, i'll be reading any of those i haven't already, although some of your reccomendations are made by japtem, and i'm already reading them. but i already read mushoku tensei, it's what got me started looking for more in the basic genre. and i started tate no yuusha, but i can't find where to read it all

For Tate no Yuusha you could use Baka-tsuki's list. You'll save time from googling every new tranlator.

The Reincarnated Princess Strikes Down Flags Today as Well (Novel) is really good. I've read a lot of the fantasy game reincarnation novels coming out, and this one is best hands down. The protagonist is smart, and the characters are interesting.
