How can this game not have built in voice chat?

[ispano]

Do you have a source where they state it is a memory issue? or is this your assumption?

Still, there are 2 versions of the game which could do it. or 3 if you count the vita's remote play.

SE has said multiple times that they have to be careful with the PS3 due to the limited memory.

... you miss the point completely, did you even read what I wrote? the PC side is fine.... but PC gamers have to interact with console gamers that have neither keyboard to type and cannot voice chat at all even with 3rd parties.

Yet the system is designed to support a keyboard. And the normal communication in an MMO is a keyboard. Playing an MMO without one is ridiculous. It's not a small group of people, such as in some FPS game.

Wouldn't common USB keyboard work ? It does work on XBox 360 ...

Yes, any standard USB keyboard will work, like they did on the PS2 for FFXI.
