So skyrim's perk system was a horrid mess of imbalance, powergaming, and remover of choice and freedom. Never do it again.

Now, we want interesting perks. Stuff like

-Mysterious stranger

- Canibalism

- Bloody mess

- Brutality

- Child at heart (but really, Only use that to make it interesting. No little lamplight Perk-or-GTFO and do a sidequest kind of thing. Something like encouraging a child to put c4 a present under daddy's chair)

- Black widow/ladykiller.

- Pointless things like doing fancy tricks to pump your shotgun, or being able to bite in melee.

- things that get you unique dialogue. Like making yourself 'All american' and become the terrible 50's american parody with a shiney white grin,misplaced optimism, love of apple pie and fear of comunism that fallout mocks.

- Being able to use stats like charisma in combat to intimidate the enemy

- Abilities like taking a human shield, falling attacks, throwing away your empty clips/weapons at the enemy to stun them, the ability to target the testicles in vats.

And if you;re currently putting in perks for weapons:

- Never put any big jumps into weapon damage. A 9mm doesn't get more powerful just because it's you using it. Weapon accuracy and reload speed is doable though. For melee weapons, your swings might be a bit more powerful once you learn how to swing, but power is going to peak at novice. After that it's all about accuracy and defense.

Great ideas, but unfortunately I wouldn't surprised if we get something closer to Skyrim's system (along with the classic fallout perks of course).

We'd need some idea how the new system works now, too much speculation at this point.

Considering all signs at present seem to indicate they're removing skills and you're going to develop your character through perks, instead... well, I wouldn't get my hopes up if I were you. Perks are almost certainly going to be gameplay affecting, not pure flavor.
