I hate hacks that have themes that have too much child themes or too much adult themes. Same thing with language. Keep it balanced like Ruby Destiny. If your best friend dies in front of you, you don't say "Nooo! Darn it! Why did this happen?!" Or if
your Pokemon got stolen, you don't say " You mother****er! Go to hell you *****bag fat sack of ****! I hope you ****ing die! I will go to your house and slit your mother****ing balls off you piece of goddamn ****!!!"
Also, finish your hack. I don't care if it's unfinished as long as you're working on it. I think a person who makes a hack thinking of only himself/herself (like me) equals a finished hack. It sounds selfish but think about. If people don't like my hack, I won't give up! If my hack is unpopular, I won't give up! If my hack has glitches in every corner,(which it does) I will NOT give up! Finish your hacks people!
Another thing, Fakemon. I just don't like it. It gives me a weird feeling, I just don't like Fakemon. There are only a few exceptions, Pokemon Quartz, the Pokemon Ruby Destiny series, Pokemon Opal, and a few others. If I like your Fakemon(don't count on it, out of the millions of hacks I've played, there are only a few I like) then congratulations, you did a good job on them. Other than those few hacks, Fakemon are the biggest turnoffs ever for me.
