You should've waited to get those games on the App Store. Just recently they had a promotion where people could get those titles for free. I've saved around $20 just waiting for paid games to become free.I bought the Hitman and Lara Croft GO games, definitely worth it in my opinion especially when they were on sale for $1. I think it's far better having those than the bloodsucking F2P games.
I haven't found a mobile game I enjoy enough for me to fork out money for it. I will not pay to get one that I can't try first as they usually are all a waste of money. So, basically I don't play enough mobile games to warrant paying for anything.
