its playable with mobile 3G device.
once I played with a friend who was using P1.

P/S:of course its not recommended tho.

u might want to check some of my/hiroshisora's livestream on twitch urself.

well, im on VIP20 and still able to play it while torrenting full speed. so yeah.

As a unifi user as myself, 9/10 you'll have zero delays because of the way the game is coded to be.
Which is damn bloody good IMO, the only time you would feel the lag/delay is when the servers are screwing up which also means it's their problem not ours.

To clarify a little on what I mentioned above, everything you see/experience in game are all moving locally in your PC.
The only thing that needs the server to communicate with you is the Players moving around in the map.
When I mentioned moving locally in your PC, it means that whatever you touch or get hit by anything, you will get it.

Basically in short, when you hit something it will send the data to the server that you've hit the target then it'll send the data back to you showing the damage on screen.
You'll feel the lag when you see the damage not showing up at all but of course don't stop and not move because as I said earlier, if you do get hit in YOUR SCREEN, you will get hit regardless despite the PC > server communication is being delayed or whatever.

Edit - To add on to what ultima mentioned about lag in lobbies, its basically like every other MMO out there when you see countless of players in one town where your PC just lags trying to render out all the characters at once. That kind of lag is unavoidable.

If you want you can take a look at this random video I uploaded long ago.


Excuse our voices, we were super sleepy when I was recording this.
