Well, let's see here.
KHI- beat it [standard]
Re:CoM- still attempting to beat (go ahead and insult me I don't care) [beginner]
KHII- beat it + beat Sephiroth + got Ultima Weapon [standard]
358/2 Days- beat it + beat Dustflier + beat Anti-Riku & Anti-Saix [beginner {only because I didn't care much about the gameplay, but rather, the story, and wanted to get through it quickly}]
BBS- beat it [Proud + Critical {includes Final Episode}] + beat Vanitas Sentiment with Ven on Proud
Re:Coded- beat it [beginner {same reason as Days}]
KH:3D- beat it [Proud + Critical] + beat Julius {both characters} + beat all Special Portals & Secret Portals {both characters}
Not particularly impressive; I’m replaying Days, KHII and KH (as well as playing KHFM on 1.5 ReMIX) so we’ll see how that goes. I’ve done some other things to the games, trophies, commands, mini-games, etc. I’m not going to list them, though, unless someone specifically asks for it (which I doubt will happen).
So, summary, I’m decent at KH, I’d like to think. I’m getting better, though.
