Demons, mature themes, samurai—blah, blah, blah. That stuff is important, but guys, look. Look at the things you get to wear in Shin Megami Tensei IV.
That scarf. That jacket. There's probably more; this gameplay footage by SCRAWLfx is short.
Either way, I'm excited. Personalization is important! The world might be rather desolate in this game, but that doesn't mean you can't look your best. Unfortunately it seems that it's not all cosmetic—stat will change depending on what you wear—but that just means you'll have to switch it up a little. Never a bad thing.
Currently Shin Megami Tensei IV is not confirmed for North America, but my guess is that it's just a matter of time (as is the case with most SMT titles). For now, you can catch up on what it's about here.
