I am playing rather slow. My char is mainly a 2-hander melee character, that joined Imperial-faction and Companions-guild. The game seems overwhelmingly big so far, and it demotivates me when planning onto starting another 2 classes: "mage" (mainly destruction) and "thief/rogue/assassin" (with backstab, etc.).
As far as I understood there are 2 factions total: Imperials VS Stormcloaks and you can only join one of them
And there are 4 guilds (Thieves Guild, Dark Brotherhood, Mages Guild and Companions), and you can join and complete all of their quests in one playthrough. But something tells me that for a best experience, it's best to join only some of them accordingly to what sort of character you want to play, regarding to "good/evil" choises and what sort of skills and perks you level up.
Wouldn't it be best to complete Companions as "warrior", TG and DB as "thief/rogue/assassin" and Mages guild as "mage"? Have anyone completed them all in one playthrough, and did it ruin the gameplay/immersion to do so?
The reason I am asking, is because this game is so huge and there doesn't seem to be any limits what a character can or can't do. It seems that Bethesda is encouraging players to try nearly everything no matter what character you are playing. This confuses me, because without guidelines, I am having a hard time taking action into one specific direction. I would rather take a planned action and have some sort of expectations on, whether it's optimal way to play a specific sort of character. To rephrase - I would like someone to tell me which path to take to get the most out of my experience, for the most amount of fun, so that the game makes most sense.
Please share some suggestions. Thanks.
