I know everyone reads reviews just to see the pros and cons of a game. But generally people read reviews because they if they know about the game all they want to read is the bad stuff.

What would you consider flaws in a game?

For example Alone in the Dark: Control issues, what else?

Repetiviness, If I get bored with a game odds are i wont go back for 2nds.

How well put together the game is, if it's controls fit together nicely, the substance and most importantly the pacing.

If it's not what I expceted or better then I expected, I will be dissapointed. Like with Mario Galaxy, Blue Dragon, Soul Cailibure 4, Halo 3, ect...

if i play a game and say, man it would have been cool if they did this really easy to implement thing that is almost obviously needed.....

Not enough cutscenes to sit through, it seems these days games just don't have enough cutscenes or they're just not long enough.

This.

Replay Value.. I need a game that lasts long =/

Poorly designed difficulty curves, lots of games turn out terrible simply because they become way to difficult or fail to pose a challenge, it's very hard to get the right mix that makes a game challenging enough that the inevitable repetition is enjoyable while not being so difficult that you waste hours replaying the same 5 minute section again and again which in my case typically marks the point where I simply stop playing.
