"Everything"? This a joke, right? =)
That'd require playing every last gig, side mission and encounter multiple times: 1st time "specced" (and properly geared, too) as a hacker; 2nd time - as a melee; 3rd time - as a sniper; etc. Same for dialogs: 1st time high Int, then after completing any particular mission - reload earlier save, respec to "low Int", play the mission 2nd time; 3rd time - similarly lowering / upping some other dialog-affecting stats, etc.
Frankly, even if there are some players who'd enjoy this sorta thing - i say hey let 'em, they still play all the content way more than once.
And if you merely meant "getting to every secret place and earning all the big rewards" - this actually does not require multiple different playthroughs even as it is, with extremely few exceptions. In general, the game's designed around "high stat checks allow easy ways in, but there are harder ways to get things which do not require high stats, but require more attention / time from the player".
For an example, there is a side mission where V is asked to take out a club owner who went too bloodthirsty when doing his own recent gig, and there is a door in the club with tech requirement = 19. Behind it is some quality loot and a bit of story. However, same room is also possible to enter by going over or through obstacles and reaching another door to the room which has no stat requirement at all. Similarly, practically all such places also have either some destructible environment (windows, vertical entrances, even walls sometimes - heck, very 1st mission where V saves a girl outta scavengers' ice bath has a destructible wall), or access rights / codes for alternate entry, or ways to jump into it, etc. Which is, indeed, good game design exactly intended for players to be able to experience "everything" in one go.
Next, what about gender / romances? Stat respecs do not allow to change gender / possible love interests, you know.
Also, it gets even worse with some player choices, you know. For example, one can betray Panam at certain point, which eventually leads to specific extra content, including getting one free (and rather fancy) car - but then, of course, one won't be driving a tank with Panam, and one won't be getting one certain specific ending, too. Stats play a role in such choices in some occasions, but most of the time they don't.
So yeah. Must be a joke. Good one.
No, not a joke. Though it has to be a joke that you assumed so much, and incorrectly, about my very short post just so you could write a tldr rant about stuff my post had nothing to do with lol. Good one.
I thought we where talking about stat points in this thread?
So, given that, I figured it would be obvious that was what I was talking about by "everything".
Meaning try "everything" as far a stats are concerned. Seemed obvious to me but clearly I was mistaken.
I wasn't talking about story, missions, gigs, etc. blah blah blah.
I was only talking about stats points as that is what this thread is about.
So yeah. Good one.
