Dont know about you, but when Fallout 1 came out and I got greedy hands on it, I think started over 5 or 6 times till I got the char I liked and another 3 or 4 times before I actually finished the game
Its part of the fun. Nowadays, we can read up on the topic before starting the game, but I still tend not to do it unless I am completely swamped with game's mechanics, like in Divinity 2. Now that game is truly overbuild beyond my willingness to invest time to try and figure it out, wiki or no wiki.
