Then.... stop playing it?
That's not the problem.
You see, my father's computer has broken down, so he's been borrowing my computer because I had the PS2 to play. The only game I have is Kingdom Hearts II, but it was at least a nice distraction while my dad swung a lightsaber around and [parasitic bomb] in SWTOR. But now that I've beat the game, crafted the Ultima Weapon, and defeated Sephiroth, there's literally nothing to do. Even walking from Cloud to a save point after beating Sephiroth and claiming my reward of sweet PS2 Tifa action, I felt so...empty. Like...killing Heartless has no point now. I don't need any items from them, I don't need to level up at all, and even if I go out of Hollow Bastion/Radiant Garden, there's...nothing. All the worlds are beat through, and I already completed the game on this difficulty...and now...what will happen when Dad needs the computer again? What will I do? Where will I go?
WHAT WILL I BE FIGHTING FOOOOOOOOR?!
