In any case, I can absolutely recommend Alinea Computer, https://www.alinea-computer.de/index_en.php, and its online shop: https://www.amiga-shop.net/en/Alinea-Computer:.:11.html
Just have a look at their games: https://www.amiga-shop.net/en/Amiga-Software/Amiga-Games:::29_53.html
Maybe yours would fit there?
AmigaOne X5000 @ 2GHz / 4GB RAM / Radeon X1650 / AmigaOS 4.1 Final Edition / MorphOS 3.17
Amiga1200 / Blizzard 1230 IV PiStorm32-lite / 128 MB RAM / AmigaOS 3.9
