The solution is simple though:

Aaaaw hell no! THIS is the solution ;)

1. Lack of depth
2. Notifications reminding me that its time to play
3. When the core game mechanic was built specifically with micro-transactions in mind
4. I'd like to use my phone's battery for something else. Hate having a low battery, especially since I love in a country that doesn't have 24/7 mains power supply
5. Adverts, especially the type that pops up and takes over the entire screen
6. Game using my limited cellular data to load ads
7. Pop ups asking me to rate the game. Just leave a rate us button in your game's menus.
8. Sometimes, console-like controls are shoe-horned into a touch screen interface. Unless a console version of the same game won't use too many buttons, this leads to crappy controls
9. Usually ridiculously repetitive because no matter how polished the core mechanics, that's usually all you can do in the game. I have badlands, infinity blade, cut the rope, republique, etc, but I get bored with a lack of level variety. My most played mobile game is Words with friends

- I find myself not as immersed with the lack of control that touch screen is limited to.
- Majority of games are quick cash grab thus the quality/heart isnt really there.

Mostly the missing buttons.
On-screen buttons and d-pads are crap.

everything that i hate almost said in here, plus it kill mainstream game industry especially the profit and market share. quantity over quality and micro transaction.

Definitly unprecise controls.

Touch controls will just never be precise and hardcore gaming requires precise control. Not to mention they cover the screen with your fingers. Its fundamentally flawed.

Eh? I hardly think that's a problem at all. I'd rather play games on a Game Boy Micro than a Galaxy Note.

This!
