If you're looking for something to play with all the grinding and leveling mechanism that you want from a role playing game, Undawn is the game to play with all it's features and storyline.
Unfortunately though, the optimization of the game engine is a lackluster, it's not very supportive to midrange phones like mine.
Last but not least, the P2W in this game is strong, might even feel stronger than lifeafter, it's not just cosmetics but actual upgrades that you can't simply get by grinding.
After couple of days it will start feeling like a full time job with a demanding boss.
