Guardians assemble
I have been playing PSO on Wii and PSU on 360 in rotating sessions. Basically one game one week, then the other game the next. Rinse and repeat. I was nearly ready to give up on PSU but then things finally started clicking after what felt like 2 hours of introduction related dialogue/content.
This game is unique with the episodic tv format intro/outro to missions, the random anime cut ins and the quirky dialog.
The movement is light years ahead of PSO. It's nice not having your character freeze in place because they nicked a corner or got near an NPC. Being able to change weapons quickly is nice and the camera controls work quite well.
My only big complaint with this is it takes a while to figure out how to navigate all the different hubs. The starter hub has 5 floors with a train and 4 different ports to head to other areas.
The second hub is split into 2 districts. One for shopping then a different one for progressing the story/repeating quests. If an NPC tells you to meet them somewhere and you need to stop playing you better hope you wrote down where you were supposed to meet them or you're in for some back tracking.
PSO is a fun, clunky game with a rewarding but endless grind and a very loosely connected story.
PSU smoothed out the movement and combat with an actual story but made navigating the Hub tedious.
Both games are fun on their own and are worth checking out.
