Graal Era... Single player?
Recently I was on a really long car ride (LIKE 3 HOURS)with my parents and I'm like, "OMGGOSSSH ME WANNA PLAY GRAAL"
But I couldn't because obviously no data or wifi.
SO.. I WAS THINKING :]
Why not have an offline iEra, basically you can use all your items and practice spars with CPUs etc.
Also it could have like a Sandbox Mode, where you can try all weapons and items on iEra but you cant keep them when you go online. This can allow players to see if they like a gun and if it is worth buying.
Plus you could just run around era and do all the fun things you would normally do like play at the arcade, explore, etc.
Just a thought. :)
