Mobile Gaming and P2W

Hey guys, what's your opinion on Mobile Gaming? I do play some, like Summoners Wars and Clash of Clans. The only thing that are very bad on them are the microtransactions, both of them do have alot of: "HEY, BUY THIS! YOU CAN BE COMPLETELY AWESOME WHEN YOU BUY THIS!"
Mobile Gaming do offer you to some extent an easy accessible game to "Hey, I don't have anything else to do. Let's just grab my cellphone and play this game."
Most of my friends think that Mobile Gaming is not a proper gaming and that they are basically P2W. What's your opinion on them?

Whch mobile games do you commend to play?
