What I see.
F1 - NW perks depends on levels, specials and skill.
F4 - perk ranks depends on level of player character.
All previous fallouts I could quickly get 100% skill or any perk rank.
For example, in F4 I can get Hacker rank 3 only at level 21. I can't use mentats to get higher rank temporary, I can't wear engineers robe etc.
BTW In Fallout 3 (no DLC) maximum player character level is 20.
Why? Yes, I can shoot from start. But is this shooter?
I can't select specialization. But I want be natural born genius! Before war I was:
1) soldier (all perks depends on weapon are unlocked at start of game)
2) engineer (all perks depends on electronic are unlocked at start of game)
3) trader (all perks depends on speech and money are unlocked at start of game)
4) athlete (all perks depends on physical training are unlocked at start of game)
5) etc
Where is RPG?
Fallout 5? I can't imagine, LoL.
