You say this, but... This is something easily sussed out with some trial and error in just a few minutes with some common sense logic. When you get to Balmora, and you find the Alchemist Shop (which I'm sure you will, because a thieves' guild quest sends you there lol) and you see she's got LOTS of reagents. A lot of them are very cheap in price. Any player who has a head between their shoulders is going to go "hum... what's stopping me from buying cheap ingredients and mixing them and selling them back as potions?" especially when they see that the shops restock immediately as soon as you close and re-open dialogue. So, after some trial and error, it wouldn't take too long (if they started with cheapest ingredients first) to discover that Scales + Muck (two of THE cheapest things Naryla sells) = Drain Personality. One successful attempt costs ~5 gold and the potion sells for ~8-9 gold at low Alchemy skill and basic alchemy tools. Wow, that's almost 50% profit! It's just.... you fail too often. Well, ok, thieves guild gives you 500-1000 gold per quest, I'll keep questing for them to build up some starting capital first. This early in the game, if you're worried about major/minor skills, again, anybody with a head on their shoulders will figure out that they should do Mercantile/Alchemy as Misc skills. 5 hours later and they have Alchemy 100 and they have completely broken the game to where money is useless because they can print money anytime they want, and they are invincible because said health potions heal HP faster than nearly any enemy can take it away and said potions weigh 0.1 lbs. This means ONE HUNDRED potions is 10 lbs. Basically, you're immortal by that point. Skyrim doesn't allow you to do this by any means. Yes, it is impossible to mess your character up so badly the game is unwinnable, but yet there are far fewer broken mechanics just laying around to easily stumble into. Before patches, you could give yourself unlimited stats at the very beginning of the game by making a 1 second Fortify _____ to get your stats into the hundreds which made you more of a deity than Dagoth Ur ever was. And you can do this about 10 minutes into the game, thanks to the friendly mages' guild having said spells for sale and Spellmaking which leads to some of the most broken gameplay I've ever seen in an RPG, like, ever.
