What are some actions, maneuvers, tactics and activities in your favorite video games that "feel good" when you accomplish them?

For me, the most resounding example is a solid Siege Onager hit in Age of Empires II. The sheer amount of serotonin my brain has released from those beautiful medieval WMDs... its amazing.

Other items include:

• Caustic's Gas Grenade getting ticks in Apex Legends
• Burning down a tree (or forest) with flint and stone in Minecraft
• Big, stompy, green trample damage punching through in MTG Arena
• Big, automated drilling rigs in Space Engineers
