Except for playing with my bros, thats how I was gonna do it. I like to explore and take my time for a first playthrough. Online I feel like I have to rush and keep up with the other players. --- When coincidence is so convenient, I prefer to call it fate.
You can do co-op split screen without going online. Screen is split but its a fun way of playing with other people you know over randoms. Online gave you the higher chance of rare drops the more players you have. So there is a third option.
if this game still uses "playthroughs" i'm gonna do playthrough 1 alone (or splitscreen depending), if it gets too hard sure i'll go online. --- RocketZXBlue on PSN In progress: Golden sun dark dawn, kingdom hearts I (ps2), phantasy star ONLINE 2, persona 3 FES, Disgaea 4, Legasista
