-Terrible controls, no buttons, wtf?
-Not serious games, lots of mini-games, and the games that try to be serious aren't as good as console ones.
-The free-to-play model is making kids tend towards the mobile market, hurting consoles pretty bad, and the microtransations on power-ups and sutff are creating soft cock "gamers".

Kill my battery.

-Micro transactions in most free games
-Really bad controls for RPG and some action games.
-The games are bad quality, gameplay-wise, I guess the low price somehow justifies it.
-Lost potential for console/pc gamers.
-Those who buy smartphone games usually buy every next game in a series, ultimately leading to lazy developed games that add nothing, really.

There's some good games though... But it's just not a good platform to play games on. It would be way more viable to develop on the eshop of Vita/3DS which has physical controls + touchscreen if needed, all your games in one place, and actual gamers. It would move many smartphone gamers to handhelds, and those who don't care about dedicated gaming devices probably don't even pay for the games on their phone anyway. iOS/Android is a quick cash grab, developers are encouraged to be lazy since even mediocre games could be selling well depending on the marketing.

on a side note: I haven't touched iOS shop for awhile, are games like angry birds and Infinity blade as popular as they were? Is the market slowly dying, with other apps like Instagram and Snapchat probably eating people free time?

I would compare mobile gaming to fast food.

It has a place and is good every once in a while but it's not enough to live on.

I have simply never played a mobile game that held my interest beyond a couple hours. After that it is either
1. Poor
2. Shallow
3. Makes skinner box paywalls as only way to advance

ps4
wii u
xbox one

1. Micro-transactions even in paid games

2. Terrible controls.

3. Repetitive gameplay

4. Too many clones/ cash-ins/ crap to go through to find gems.

5. Kills my battery life.

- Controls

- Lackluster and pretty much meaningless experience

- And above all, microtransactions to the max. Although we have that too on consoles, mobile games are built on that shit.

- Touch Controls

- Microtransaction in most iOS/Android games

- All mobile games suck major ballz except for Infinity Blade

- Breath Of Fire 6 turn into a mobile game

- Lame-ass shitty bird games ( you know what i am talking about )

- Rip-off customer by making them pay a heavy sum of cash where the game offer less content and not worth to play

I really enjoy the puzzle, gem, bubble, card type games, something I can pull out on a 5 minute break or something, but I absolutely refuse any micro transaction crap.
