What do you miss from previous titles?

[Jakosifer]

PSO: RAcaseal skirts, Daylight Scar not sucking, CCA is still the best area in the online games.
PSU: Ethan Waber
PSZ: Best Slicers. Best Shields.
PSP2/i: The grinding system, class customization oh my god ridiculous.

How bout u?

[HFlowen]

PSO:
-Special attacks
-Static level layouts are more memorable than cookie cutter block layouts randomly attached to each other.
-Quests that require teamwork and puzzle solving to advance (pso2 has this with that one time attack quest)
PSU:
-Protranser
-Bows, I liked bows
-Enemies that posed a threat to the group and required planning and use of status effects to take down quickly (build-a-bears)
The rest: Dunno, didn't play em.

EDIT: I'm probably gonna update this post like, fifty times.

[sugarFO]

PSO: Tech spamming, awesome levels (caves, CCA, seabed), awesome music, creepy subtle story, being a support FO, my armor that made hearts float around me
PSU: tech spamming, lots of pretty costumes, my armor that made hearts float around me (yeah I really miss Safety Heart ok)

Dunno what else, PSO2 is pretty good otherwise.

[Shakuri]

PSO: Our characters seemingly being intelligent enough to grind their own weapons.
PSU: Drawing a blank here.
PSZ: HUcaseal looked so god damn cool.
PSP2i: lol, what I don't miss is a better question. I did hate hunting drops that were exclusive to Infinity missions...

[blace]

PSO: Grinding without worry, and episode II.
PSU: Being able to level PA/Techs by using them or finding stronger disks.
PSP2/I: Grinding equipment came with a cost, not chance and rebirthing.

[moorebounce]

PSO: Dropping or trading items for free.
PSO Xbox: Voice Chat
PSO GC: Split screen

I miss in PSO where you could actually combo before the monster moved.

[Miyoko]

Weapon variety and rares that're actually worth a damn.

[Quatre52]

Challenge Mode.

A Community that enjoyed the game instead of complaining..

[PrinceBrightstar]

Classic/Algol: Megid that fills the screen with the fires of hell and not a purple ball of sometimes death, a great story.
PSO: Hunter's Counter quests, Challenge Mode, Love rappies during Haloween
PSOIII: Such a unique game and a shame it isn't supported anymore.
PSU: Character + Class Levels
PSP2i: Rebirth
