I mean, maybe it feels better after a full games worth of content, but just the idea of having power ups from achievements in of its self seems like a very not fun thing regardless of if you have 25,55,75 or more achievements unlocked. You don't usually get extra power ups that transfer to new saves in a game just by getting achievements. It rewards and pushes for a particular playstyle.
But hey, maybe it's only a few of us who think that the system is really silly and would rather just bypass it by playing silly in one playthrough then fun the next or just cheat unlock and be done with it. No need to change something that other people have fun with. No big deal in any case. The nay sayers can work around.
The price of 50 to purchase skill points is definitely too low compared to $10k cash for 200.
Around level 10, you can earn like $500 per day working, so making that sum in 20 game days, ignoring the daily stipend income. At least with stamina_boost1, it already takes around 30 days from level 8 to 9, depending how many free actions you have available and use.
Taking all the stamina_boosts will surely reduce that time much more, but they all cost 9 points alone too.
With my current 730 a-points available on a restart as example, someone could purchase like 14 skill points what is almost every perk (16) or most useful mutant abilities (19) with the current pool available.
If the level cap will be 30 later, what looks tiresomly unreachable enough giving the hefty increase of XPs/level, then at least 5 skill points must come from the achievement pool, but only if someone really has to obtain everything.
Of course you don't really need every gimmick enabled. By increasing the price of skill points, you add at least some challenge again and force to make a plan what to rather pick or not.
Picking something like stamina_boosts is way superior to everything else like an anal x-ray vision for the fun out it, but if there are players who enjoy the grind then why not give them all the fussy extras to toy around as well. Some rewards for wasting one's lifetime should be granted.
More than a half of all achievements can be done by not paying attention while others are hardly done in a regular session, like skipping class for a week.
It's understandable that achievements are meant for doing them in more than a single chapter, but the temptation is still too great to grab them them early to make one's playtime easier should v1.1 hit one day when at least I will certainly start over again; not due a-points but due every basic feature available and polished. I'm looking forward for the full game experience right from start and maybe I still find some leftover bugs meanwhile.
If the price of skill points gets increased to 200 as well then it shouldn't really make such a difference anymore, but having currently effectively 14-15 extra levels as skill points available right from start surely feels too much like cheating.
Otherwise, I wouldn't mind removing the option to purchase skill points for good either.
I'm also afraid you can gain too much money later without enough money sinks available, but let's see what stuff and activities are still added the next half year.
