Personally, I kinda liked gaming on Android - and also kinda hated it at the same time.
I liked it because there were good games despite their issues, such as:
Fate/GO (Good story, but plagued with gacha hell & unreasonable root detection)
SAO - Integral Factor (Fun, free, gacha hell)
Animus : Stand Alone (paid)
What I hated about gaming on Android:
License checking - Any paid games from Play Store ; for example, the aforementioned above Animus : Stand Alone, requires Play Store License checking. That, in my point of view, means that unless the owner of a paid game has signed in with the account they used to pay for the game, they may not play that game.
Gacha Hell - Includes Fate/GO & SAO - Integral Factor. Sure, with enough skill & experience, this issue may be bypassed. But, for the fanbase, getting the SSR they want in these games, for example, requires either sheer luck and/or real-time money. Sorry, but I'm not sorry to say this out.
CAPITALISM - sorry, gotta say that one in full caps. But, microtransactions.
Not fun enough- Honestly, other than the 3 games I mentioned above & PUBG Mobile, I don't think any other Android games are fun enough. Sure, I can sidestep this issue by playing retro games with emulators, but, so far, the only good emulator is PPSSPP - DraStic, a DS emulator, requires Play Store license checking.
Mandatory Internet access - Most Android games are digital release only. Fate/GO & SAO-IF are also plagued with this issue, as both were incomplete on release. Sure, updates do fix bugs & add more content, but, single-player games requiring internet connection scares me about the future of gaming, especially on Android.
An example of a game that (kinda) bypasses this flaw : iPad's Infinity Blade series (discontinued & removed from App Store, unfortunately). The only times it actually needs internet access is for cloud saving. However, it still relies on the App Store; as it's a paid app (license checking).
