What's a good Android game for a guy like me who likes strategy but doesn't have a ton of time to waste?

Look, I don't have hours to sink into games anymore. But I still like a good strategy game. Age of Empires Mobile hits the sweet spot. The matches are quick, maybe 15-20 minutes, so I can actually finish a game on my lunch break. It's not some dumbed-down mobile game either; you still gotta think about resource management, unit types, and all that good stuff. Plus, the graphics are decent, which is a bonus. It's not going to replace the original PC game, but for a mobile game, it's surprisingly engaging. I can hop on, play a quick match, and get back to work without losing the whole afternoon. For a guy who appreciates efficiency, that's worth something. Bottom line, it's a good way to scratch that strategy itch without sacrificing my entire day.
