You can only get the bonus points after playing long enough, I was basing my post on the assumption that the poster was new to the game.
It is true though, getting the Achievement Bonus Points allows you more access to content overall.
Well, not necessarily more points mean more content...
Personally, I go with high charisma first (8 will do), since several options have the highest stat requirements as CHA (8 max I think). That solves a lot of problems as well unlocking content.
Then I invest in Magic (at least 5) since I think 5 is the highest requirement (might be higher now with new content). Again, it solves a LOT of things (Alma content, Golem, etc) content-wise.
AGI/END goes next, there's plenty of checks, and content is decided by passing or failing.
I don't think I ever had more than 2-3 strength.
You can complete the first map without even buying stat points... as long you're "willing", if you know what I mean *
overexaggerated wink*
That being said, there's content you won't unlock unless you start over.
Aside of Bad Ends (which technically cut your game), some content gets locked when unlocking other. The best example is the Unicorn and the Golden Pig. If you choose one, the other gets locked (since requirement is virginity).
Becoming impotent also locked content (but I think now it doesn't).
Max strength (or 8-9) is (or used to be) insta-game-over with the Werebitch, meaning you can't access some of her content, as well the Gadgeteer in similar ways.
Getting certain... features? what are they called? Like anal lover, or cuckoo for birds, will lock you out too.
Stat points sure help on certain situations (the Spider cave -
which I avoid like the plague... yuck- for example requires lots of stat checks to pass thru, and most fails are bad ends), but is the
decisions that count.
For that you need to choose one or the other, with one locking the other or viceversa.
Basically:
you need to do several runs (maybe 2-3) to see everything.
Or just go for the stuff you're really interested (I haven't seen some content at all, because there's stuff i'm not interested, not even by curiosity), which is much faster and can be done in 1-2 runs.
