I'm a lifelong gamer who's entered a bit of a rut these past few years. I would
love to pay to play great apps on my phone. But I don't have the slightest clue as to how to find them. The top grossing lists are all complete F2P junk, and there's nothing close to the cottage industry that's built up around PC and console gaming. Every time I try to go look up good mobile games I get hit with lots of dodgy top-10 compilation linkfarm spam sites. I don't even know where to go to find the best mobile games, and every so often after investing another ten fruitless minutes of research (into what should be fun!) I'll give up all over again.
Contrast with my recent gaming experiences on the PC -- Civ V, The Witcher 3, Kerbal Space Program, and Faster than Light. All excellent games well worth their price that I was able to find out about easily. I don't know if anything comparable exists on mobile gaming, or if it's all just shit, nor do I even know how to find out. Back in the day Sony and Nintendo owned and published official magazines that were excellent sources of finding out about games, and many other non-official rags filled any potential void left over (I'll forever look back fondly on my afternoons after school spent reading issues of PC Gamer, PSM, and EGM cover-to-cover). Nothing comparable exists for mobile gaming, and Apple and Google could be doing a much better job of curating their gaming content.
