In gaming, is there anything that you can't have too much of?

Too many characters normally ends up a problem-the characters aren't developed.
Too much storytelling-and the game might not feel game-y enough.

Loot-filled RPG's. Usually, no matter how rudimentary, if there's a crapload of loot, it will be awesome to some degree.

Too much gore.
 
Too much violence.
 
Too much shooting.
 
Too many people to beat up.
 
Beat them ups and FPS are too much.
 
Also, CREDITS!!!!!!!! These days, game credits are longer than a half-hour TV show. Well almost. One game had a credit scroll that lasted 20 minutes, 2 minutes shy of a TV program.

First person shooters.  As long as the gameplay looks good I will keep buying them.

Too much awesomeness.

2D Castlevania games.

Too much of anything is usually a bad thing.

Strongly written, well defined, great voice acted characters. Gaming in general has been way too story focused, they neglect to realize good characters are as if not more important than overall plots.

halo skillz?

Can't have too much of a great game! whoa, yeah!

You can never have too many voice clips for stuff that happens commonly. IE: enemy death sounds, random stuff NPCs on the street say, things for Claptrap to yell out when I'm checking the bounty board, etc.

Ammo. Never too much ammo.

There can never be too many...
 
Enemies on screen.
Exploding heads.
Dead bodies.
Guns.
Pyrotechnics.
Dust clouds.
Bullet tracers.
Polygons.
Pixels.
Normal maps.
Shaders.
Physics objects.
Dynamic lights.
Destructible walls.
Gigantic boss battles.
Violent execution animations.
Cute blob creatures.
Lines of non sequitur dialogue.
Shrubberies.

You can never have too much loot. I used a trainer on Titan Quest after I finished it so that every chest would drop like 140 rare items. Still wasn't enough for me.

(A) Leveling  -  Every game is made better with leveling.
 
(B) Exaggerated Breast Physics  -  See above.

" Too much gore.  Too much violence.  Too much shooting.  Too many people to beat up.  

Price drops.  Cant have enough of those.
Demos, every game released should put out a demo. 
 
There are too many JRPGs and not enough real rpgs.  Games where you play some boy that looks like a girl and has to find his destiny with a friend who is a summoner are all too common.  How about more games like Oblivion and Dragon age, mass effect?

Free time.

Humor.

Skills. You can never have to much skills.

Can't have enough games with point allocation. I LOVE POINT ALLOCATION!

Good games.

Boobs.

There are to many credits that are way to long but you can never have to much area detail.
