Now, guys, I want to ask an honest question. Is it viable to change your idea for a build, let's say, halfway through the game and not suffer miserably?
I find character development in RPGs to be fun when you can adapt to what the game offers, well, like a reasonably intelligent person would. There is absolutely no reason in Fallout to tag Energy Weapons at the start or invest in the skill. You can start doing that when you actually have access to the weapons and decide to go for it.
In W2, do I really need to start with a predetermined idea for builds for my chars and just unlock consecutive levels of the skills I had chosen at the beginning? I'd love to be mistaken, but that's a significant factor in the game felling quite boring to me.
It's possible, of course. However, when getting to California there's a sudden stupid spike in difficulty, which wouldn't be a bad thing if the game wasn't developed by people who don't actually play games and interns recruited from forums and therefore the difficulty spike means HP bloat and suddenly every enemy has insane armor.
And I suspect that no matter how well you build your characters before, you'll still have some troubles or at least annoyances here until you get better gear that's designed especially to beat these new enemies with their high armor. Because like in every RPG with shit design (or modern RPG) the gear is about 10 times more important than how you built your character.
So, really, you're better off just not playing it at all. The game is shit on all fronts. There's nothing that makes it worth it... shit combat, shit writing, shit systems. The game is filled with turds, both literally and figuratively.
