1. i got already 3 times asked for my opinion in the game, does it have any effect on the outcome?
2. i also got shin megami tensei Nocturne, does it matter which i play first?
1. Yes, albit in the long run. If you want to know it will determine some skills you get and influence
who you get in the last dungeon of DDS2.
Also, if you want to know what to do to get all the "right" answers for 1 then
pick the top option every time.
2. No, but I found DDS helped me better get the battle system to do better in Nocturne, I think by familiarizing myself with spells/abilities without having to throw them out or hope I have the right demon that knows them.
Edit: I forgot Code never got changed to spoiler! Sigh.
