Fire emblem heroes

Kotor.

Fire Emblem Heroes just came out, so...

Final Fantasy Brave Exvius definitely. You don't need the best units (super hard to get) to be able to clear high end content so far. The pixel art in this game is awesome, really fleshes out characters from older games. But a lot of them aren't useful after a point in time. As is customary for gacha games.

I was so skeptical of Fire Emblem Heroes but it's such a great addictive game! Not quite as involved as the mainline series, but what you get for free is a top notch SRPG experience.

I'm looking for some good F2P ones, and I just can tell you to avoid Zenonia 5 like the plague, its double game currency system is the worst of every F2P game I ever tried , if you don't pay you get the premium currency in horribly low amounts, installing sponsored games or doing other sponsored activities gives low amounts too. What's worse, the magic objects, weapons and armour enhancement system is as flawed as Enchantment in Morrowind, although it's not as low-powered, it even has higher probability to fail, not only consuming the enhancing gems for nothing like Morrowind, but also destroying the objects you wanted to enhance, unlike Morrowind, and unlike Morrowind, you cannot at least raise success rate using Alchemy to recursively produce higher and higher Intelligence potions.
A potentially decent game is made frustrating by their greed.

I don't know if you like these type of games but what about Clash Royale? Started 3 weeks ago with it and I am enjoying it.

Found out about Polytopia just before the holidays, and only played that mobile game for the following month.
Nice and simplified civ game, perfect for mobile.

Lux DLX, Influence or WarLight for risk based game

Age of Strategy for standard turn based strategy, but if I remember correctly the UI was strange on this one

I'd recommend Battleheart for some real-time strategy in mobile format, there is also Rapture although it's a bit quaotic.

And while searching for the links I found this other one, looks interesting

For a SRPG, the best is Growlanser: Wayfarer of Time. The best underrated SRPG ever made. Better than any FE (imo)
