Is seems most RPG games have this dilemma when you need to make a decision. In order to make the character most powerful, there is usually only one way for your decision making.
E.g. In skyrim, being an assassin w/ specific alchemy, enchantment, smithing, sneak, archery and dagger perks seems to be the easiest way to go through the game, and there are certain sides u need to pick to make u stronger. But how could u know all these w/o checking the wiki or UESP the first time u play it? And do u always feel comfortable w/ ur decision? I originally like to be a destruction mage, but it doesn't work in the later stage, even with that magic balanced mod. So I have to choose to be a melee/sneak oriented type.
I have to check out game wikis frequently and even make decisions I don't truely like to make my character more powerful in skyrim, fallout 2, 3, nv, oblivion or whatever games w/ RPG element. Starting it over gives u a second/third/xx chance but the overall plot is much less attractive than the first time. I don't like spoilers from game wikis nor to be forced to make an optimal decision and it makes me feel the game is playing with me other than being a role player.
Some gamers might share the same feeling with me, but it there a solution to this dilemma?
