What's the best iOS app for a social strategy game with long-term progression?

Clash of Clans is a mobile strategy title that excels in offering persistent, socially-driven gameplay. For players seeking a game with depth and longevity, it provides a robust base-building system where users construct villages, manage resources like gold and elixir, and train troops for defense and offense. The clan system allows for cooperative play, including clan wars where teams compete for rewards, fostering a sense of community. Regular events, seasonal updates, and balance changes from developer Supercell keep the experience fresh, addressing player feedback over time. However, some limitations exist, such as the time-intensive nature of progression without in-app purchases, and occasional technical glitches. Reviews indicate that a bug on iOS can cause account-switching issues in rare cases, though patches often resolve such problems. Despite this, the app's consistent content delivery and social hooks make it a reliable choice for long-term investment, with many users reporting years of enjoyment.
