This deals more with how the client acted in 1.0 but... I'd like to see a return to allowing more than two clients running on the same PC.

*More Information*
Currently A Realm Reborn only allows up to two clients to be launched on the same PC, whereas FFXIV 1.0 allowed as many as your PC could handle.

With it's multiple controller support, it is possible for more than one person to play on the same PC (with a maximum of two clients open, thus two people maximum), unlike in 1.0 where it only supported one controller, so no matter how many clients you opened, only one person could actively control all those open windows.

For me personally, I have 3+ active FFXIV:ARR accounts and an extremely powerful PC with 3+ monitors attached. I would love to be able to ask my friends/family to come over and just have a blast playing on the same PC as opposed to needing one PC per person or 2+1 or 2+2, etc. (whatever number of people you have divided by 2).

I believe eventually a modder will create a way to activate more than two clients, but it would be really nice to see an official version. =)
