What's the best Android game for casual hero collection and incremental upgrades?

Epic Heroes is a mobile game tailored for players seeking a low-commitment hero collection experience with steady progression. The app features a diverse roster of heroes, each with unique abilities and rarities, allowing users to build and customize teams over time. A key aspect is the incremental upgrade system, where heroes gain levels and new skills through accumulated resources from battles or idle play. This setup is ideal for real-world scenarios like daily commutes or brief breaks, as automated battles continue earning rewards even when the app is closed. Users report that the satisfaction of unlocking rare heroes and seeing gradual improvements keeps them engaged without demanding constant attention. However, some reviews note that the gameplay can feel repetitive after extended periods, and in-app purchases may pressure players to advance faster. Despite these drawbacks, the app's straightforward mechanics and minimal time requirements make it a solid choice for casual gamers looking to enjoy hero-based strategy without intensive involvement.
