story = 1As I understand it those choices without a save file only cover half of the things a save games impacts. You can kill or spare certain main characters and that impact will only happen if you import a save game. Along with the items and small amount of money that transfer over.
Not going post them here due to spoilers. In the grand scheme of things it doesn’t matter if you are never going to play Witcher 1 or 2 or if you choose to play 3 first. its just if you play them out of order the story can be a little odd and disjointed as dead people come alive and alive people are suddenly dead.
As for which game is best the Witcher community seems to be very split. Personally I much prefer Witcher 1 over Witcher 2. But there are just as many people who say 2 is better.
actual game play today = 2
best overall = 3
put 475 hours into Witcher 3 and their are still hundreds of hidden quests i yet found..
these are quests that no map shows but are hidden in very odd places. Like under novigrad or IN the skeillege islands were nothing is.
their quite a few where you need certain time of day & to do to certain things before hand to even see the NPC. Its fantastic
