As a stand alone game I would give it a 7 from what we have seen. As a Fallout game I would give it a 4 on account of the Leveling system, dialogue dumbing down alone, because the quality of the writting (despite me not being too hopeful about it) isstill up in the air.
What is your issue with the leveling system? BTW I'm okay with skills being added in the perk tree,cause the 1-100 didn't work as well as it could have.
The fact that it just doesn't work.
It actually gives the player much less flexibility and build options. Most of the perks aren't even interesting, some of them are just gates for things that where normally part of the natural level prgoression.
Skills have been folded into Perks, and by doingso not only did they completely made the level to level experience less rewarding but they also turned perks into a routine of Percenage increases. With them even locking content that was generally available activities in the previous games, like Crafting. Skills in the previous games would give you inmediate results to the basic abilities your character had with Perks serving as special rewards what would give you unique effects. Lots of perks even had cross over requirements so you were encouraged to mix skills and not just put all points on a single one, SPECIAL stats also played a very important role in that they were very hard to permanently increase and they also served as gates to MULTIPLE perks at their highest levels, but having a low stat was also a risk as they directly influenced things like Skill points received per level up, the accuracy of your weapons, the chances of finding good items (or in the originals,positive random encounters) so there was also a level of risk reward involved.
New System tho? It rewards you for having low stats because all the SPECIAL stats do is generic and simplistic combat bonuses. With charisma dominating all dialogue options. The lack of a level cap and the fact that you can increase your special stats every level means that you are also not really being rewarded for putting more points on a SPECIAL while at the same time you barely have to worry about any risks because the effects of the SPECIAL stats are negligible.
You get ONE perk, for every level of the SPECIAL stat, with many of those perks being either Worthless or redundant with one another. For example Night Person is the Perception 6 perk, gives you a +2 temporary boost to Int and Pe during the night, because it is a temporary boost it means that it isn't taken into account when leveling up, and if you want to get the perks on the higher levels of the same Stat you are basically better off not wasting your point into it, because again, Pure SPECIAL buffs have no real effect, they no longer have any Skills to give little pushes to.
Are you going to sacrifice the bottom row of Inteligence perks just to get a passive boost during the nights? makes no sense, the perk became completely worthless by the very system it is in and there is no alternative to it, so you either pick 5 PE or 7 because 6 is worthless.. The first rank of the Endurance 10 perk gives you a +2 to endurance during the day.... but you have to be maxed out in endurance to get it, and if you are interested in Strenght boosts you might as well just level up your strenght with the Level zero perk as itwill also give you access to the Perks of those 2 levels....
There is a luck perk that is jsut a random chance to get triple XP, and you have a better chance at it with low intelligence... Low intellgence decreases the EXP you gain, it also doesn't give you any other perks, which is the reason why you even level up at all. So you get triple the amount of the reduced amount of Exp you are getting instead of the full benefits of putting points into Int.... you get the most worthless perk of them all with 1 in INT, VANS, which doesn't even have a second rank. So Another Useless perk on both sides.
It's just a mess.
This has also made Chems very much worthless too, with Mentats becoming a straight up minor EXP boost and nothing else.
The only SPECIAL boost that is worth a dam is Charisma and Strenght.
And that's just the tip of the problem.
