Heh.
Seems like it's compulsory to dislike RPGs with shallow characters (then again, who's surprise, folks?) Endings seem awfully important, too. Some of you seem so infernally hard to please, your standards are set so high. I don't know what to do to make you all happy! (╯°□°)╯︵ â”»â”â”»)
But seriously, folks.
Hmmm, myself....it honestly boils down to a few things that turn me off from an RPG:
1) Need I say it? Stale, undeveloped characters. It's not that hard to write the occasional crazy character, trust me.
2) Plots about demons/angels/vampires. I...I just....no, guys. Noooo. About 1/1000 of these types of plots actually have substance. 999/1000 it's just a melodramatic story about angsty teenagers and or/adults who take everything way too seriously and bicker about power, brutally mutilated versions of existing religions and violence. This is my cyanide right here.
3) RPGs without comic relief. Most of the best games have at least one well-developed 'comic relief' main character, or a pair that bounces off each other. The best comic relief is woven expertly into the story without making people cringe.
Good Examples: Brook/Usopp from One Piece, Nanami from Suikoden II, Raven from Tales of Vesperia....
Bad Example: Jar Jar Binks. Moving on!
Y'know, ultimately, I don't care what the gameplay is like. I'm odd that way. Let's put it this way--familiar with the Fire Emblem series? Yes? Take a page from their book when it comes to writing your characters. No, wait....take 100 pages. Go play, or watch a playthrough of Radiant Dawn and Awakening. Gregor is happy you do this, yes?
I'm gonna go ahead and top it off by agreeing with Milton Monday. I was there to see the age of ripped graphics/music in the RM2K and 2003 age, and if you think Final Fantasy ripoffs are problem these days...hoobooy, 10 years ago was madness incarnate. If you would like to make a fan game, that's great--but if you cannot create original resources, or resources that someone else made and distributed (not rips!), then I'm not gonna enjoy playing the game. I make a joke about people having high standards, but I'm a stickler for rules and effort--if someone's too lazy to make/gather resources, or learn how, I can't bring myself to believe their game will be any good.
