Nevermind the commissions, it's too late now.

Things that are in EVERY JRPG:

5: Spunky immature male character who generally likes to rush into battle and learns a valuable lesson about being an adult and shit.
Most Final Fantasies, all leads from the Grandia series, That prick Adell from Disgaea 2, Sora from Kingdom Hearts, ect.

4: GIGANTIC SWORD that weighs five pounds.
Seriously, everyone knows this cliche. Obviously FF7 is the most well-known, but again, every Final Fantasy is guilty of this one, and plenty of others. In fact, we barely bat an eye anymore, it's become so common.

3: The freaking circus!
Or at least some sort of festival in town. Sometimes there's a creepy ringleader who 'knows too much', which is usually meant to seem 'mysterious'. Usually in more mysterious alternative titles. Okage, Dark Cloud, Star Ocean, White Knight Chronicles...

2: That scene in the beginning where your mom comes in and wakes you up.
I didn't notice it for a while, but there are a LOT of RPGs that start with you and your mom interacting in some way. Pokemon is classic, of course. Chrono Trigger did it, the Grandia series did it in several ways throughout the series, even my beloved Okage opens with your mother being all motherly. This probably relates back to the 'spunky male lead' because he's usually a teenager. I guess to relate to the teenagers playing the game or something. Really all it does is remind me of my TRAGICALLY BROKEN FAMILY LOLOLTHANKS.
Alternatively, sometimes your parents are just dead.

1: Pretty white-haired anime bad guy.
Sephiroth wasn't the only one, trust me. I'd give a list here, but it would actually be shorter to give a list of games that did NOT feature a white-haired villain. Or at the very least, a white-haired 'dark' character who helps you but is seemingly neutral or mysterious.
