SUMMARY Since simmers are becoming more sensitive to object limits, I decided to try adding skill books to the bookcases rather than requiring separate skill books – gotta conserve those OBJDs where we can. I’ll still make separate skill books, but they’ll be optional or mod-specific. Still makin’ progress….

FINE TUNING PROTOTYPES

A whiteboard to learn/teach the skills.

A template for custom skill majors (IN TESTING).

A functioning study book.

A working notif that displays skill trees (WORKS).

RESEARCH & CODING

Adding "study X skill" functions to all bookcases (almost forgot about loops!)

a template for custom skill careers

options to walk/drive off-lot to do skill-related things in the background (code is there, just need to plug-in the skills and give each outing a name and time frame)

CUSTOM SKILL TOKENS UPDATED VERSION 3 – JULY 2026 (CRITICAL UPDATE – REDOWNLOAD & TRASH ALL OLD FILES)

Tokens have been re-grouped and consolidated. Instead of 170+ OBJS, there are around 20 now - and you can choose which ones to play with!

Stacked Skilling. A sim who studies baking can sometimes score a few more cooking points at the same time. This sim might also stack teaching or leadership points while leading a confectionery class downtown.

Skilling for Cats/Dogs. Fluffy and Fido will be able to build custom skills too!

Bucket Lists, Collectibles, Romance, Fame/Infamy, Prestige, Theft/Petty Crime, Health Conditions, Advanced Degrees, and Supernatural abilities (aura, charge, thirst, blood rage, ghost mastery, and so on) will give your sims lots of opportunities to show off their news skills.

GET THE UPDATE HERE

Published: 10-13-2025 | Updated: N/A SUMMARY What do I have planned for the future? The list is...never ending and ever growing...how much of it will get done/uploaded and when is the million dollar question. I have a lot of WIPs (“works in progress”) and hope to get some new sections of the site open. There will (of course) be plenty of business, build mode, and hood deco things as I get my lost-but-now-found futurist save up and running. I plan on updating some ANIMs (animations), text strings and collection files on older sets as well. I’ve got some ambitious plans for custom skills/traits. So as far as mods go, let me just say….tell your sims to save room for me in their inventories. *cackles in BHAV edits* CUSTOM SKILL PROGRESS! The learning curve for the type of BHAV coding I need to do is not as steep as it was at the beginning of the year...but there is still lots to do/test. I hope to have the first mod(s) out this winter. Here is the latest on that... 1. Unique properties can be assigned/tracked to a single token so instead of 170+ tokens, we'll likely end up with 20-ish (i.e. 20-ish OBJs...not 170+). I'm planning one token for each “skill tree” (i.e. a culinary token for all cooking/food related skills). This let’s you discard skill-related stuff you don’t use.

2. Custom skilling is possible for cats/dogs on a limited basis - the testing is going okay so far! Hopefully, Fluffy will be able to hunt, forage, and more for perks! 3. I'm planning just 2 REQUIRED objects for ppl who need to conserve OBJ counts - the skill token, and either the skill book (study/teach all skills in a single group) or skill board (to study/teach all 170+ skills - likely a 3t2 or 4t2 whiteboard).

4. Custom skills should build faster than normal/default skills since they’re extensions of those. Custom skills unlock based on how many default skill points you have – look at the (planned - not final) cooking skill progression:

cooking 01 = foraging cooking 02 = canning, juicing cooking 03 = homestyle cooking cooking 04 = herbalism, alchemy cooking 05 = baking, soul food cooking 06 = confectionery, nectar making cooking 07 = juice fizzing cooking 08 = mixology cooking 09 = gourmet cooking 10 = gastromancy

This is ONLY the number of cooking skill points needed to unlock the rest of the Culinary tree – you do NOT, for example, have to master herbalism BEFORE baking, juice fizzing, or soul food…herbalism is just easier to unlock. Each custom skill has its own 10-point scale of difficulty/perks.

*all images in this post are testing/mock-up images - nothing is finalized yet. OPEN TO SUGGESTIONS/BRAINSTORMING SESSIONS - SEND AN INBOX MESSAGE. BE POLITE PLEASE.

I was also wondering why you put for example photography in the mechanical category. wouldn't it make more sense in the creativity category? (same also applies to stuff like stoneworking/woodworking, but that makes a little more sense to me in the mechanical category than photography.) sure, there is some technical know-how to being a good photographer, but without the necessary artistry/creativity and the right "eye" for aesthetics, you won't be a good photographer, no matter how many expensive lensens and other doodads you have.

on the other hand, I don't quite get why skin care is under creativity? cleaning would make more sense to me, since barbering falls under cleaning as well. stylists usually do both hair styling and skin stuff/make up, so they kind of belong together imo.

not meant as criticism, just some thoughts I had while reading your post. very excited to see where this is going!

SUMMARY The skill-building system in Sims 2 feels limited alongside the complex personality system and custom traits. Being a decent pianist shouldn’t automatically make it easier to paint, spy, DJ, garden, become a career slacker, work as an architect, and play every other instrument in-game. By default, sims can develop at least 40 skills - 4 toddler skills, 7 basic skills, 4 hidden skills, 6 life skills (AL/FT), and 11 talent badges (OFB). This CO2 skills pack expands the existing skill-hobby system in Sims 2 in the following ways:

60+ new skills taken from other games in the simsverse (Sims 3, Sims 4, console titles, etc.).

100+ new skills related to university majors, career tracks, and popular mods from the simsverse.

Separate skills for various instruments, arts, and crafts.

Skill up in several ways - whiteboard, podium, skill books, and travel interactions (walk/drive to…).

DETAILS Basegame Compatible – but skill-related objects and mods may require expansions.

Skills are invisible tokens activated by certain interactions in-game.

Sims can’t develop the same skill twice or gift them to others.

These are TOKENS ONLY - custom objects, mods, majors and career tracks which use these skills will be published on this site under the #co2skills, #co2careers, and/or #co2edu  tags. Modders, feel free to implement these and if you do – please share!
