If you want to experience the Amiga ecosystem in 2025 without touching hardware, the easiest path is:

WinUAE (Windows) or FS-UAE (Mac/Linux) — great defaults, easy setup

Install Workbench 1.3 or 3.1 plus: Directory Opus, Diskmaster, WHDLoad

Use curated packs like Workbench 3.X ClassicWB so you don’t have to configure everything manually

For games, WHDLoad bundles are a massive quality-of-life improvement over floppy juggling

You’ll get 90% of the “Amiga feel” without hunting vintage hardware.
