What Pillars of Eternity to buy? (Pillars of Eternity)

Good evening, everyone.
Played this game, met a bug, and scored.
Recently passed Spell Force 3 - honestly in the end, they scored on reading and so on (a lot of bugs, well, it's norms game, but shoot fire, its not damage in General to the complex, he passed almost the whole game without troops, some heroes). In the end, not impressed...
Here I read about Pillars of Eternity 2, and decided to go first to the output of the 2 parts.
Went into steam and I see there is 5 purchases can be purchased. Please tell me what to buy or need to buy?
