For those who prefer (one of) Sims 3's style of writing, here is the S3 version of my Nooboo Franzi & Pixcellence fonts. You can have both version installed if you'd like, but only the letter and letter-like glyphs differ. Numerals, punctuation, diacritics, and other symbols are the same.

Nooboo Franzi was inspired by the all-lowercase font Baby Lexi by Vanessa Bays. I added a bold version to match the first version!

Pixcellence is a skinny, pixelated Simlish font.

The The ~{Sample Text}~ at the bottom of the preview pics reads:

OMG, what the pl*m?! || 23 January 1992 || I <3 The Sims!
Franzilla quickly jots down her list of sixty-five bad pangrams.
A shy pink quail flew over the jinxed cyborg maze.
Cover Egyptian jukeboxes with frozen denim quilts.


NOTES
These are but plain, simple fonts.
- They will NOT affect the fonts in your game(s) simply by installing them.
- The Sims game(s) and/or expansion/game/stuff packs you have do NOT affect which fonts you can use. Heck, you could not have a single Sims game and still be able to download and use any of these. I'm not quite sure why you'd be on this site though.
- These fonts should be compatible with any program that allows the use of .ttf files. However, if you install them while said program is running, you might have to restart the program or refresh its font cache.
-You may have to adjust some kerning pairs. I'm still working on perfecting this!
