If you really like the first two Age of Empires games, you might care to check out Stronghold HD. It looks and plays a lot like AoE II, but the emphasis is on attacking and defending castles, with each scenario having you do one or the other. For example, if defending, you would put up towers and walls (or, if they're provided, fortify them) and then station your archers in and along them, and maybe surround the walls with pitch that you light on fire when the enemies walk in it. If attacking, you might approach and try to scale the enemy's walls with ladders or build siege engines and try to bust a hole in an weak point so that you can send your soldiers flooding in. The original Stronghold is from 2001 (i.e. AoE II era), but Stronghold HD is a version updated in 2012 for higher resolutions and modern Windows (i.e. basically just like AoE II HD). I missed the original game in the 2000s and didn't play it until the HD version in 2015 and loved it, so it still holds up. There are a bunch of sequels, but the original is the best, especially if you love the early AoE games.
