I used to collect Pokemon cards when I was a youth. I grew up and my Pokemon cards collected dust (and I learnt to be a software engineer). Then one day I stumbled across https://poke-holo.simey.me/, which is an incredible piece of virtual Pokemon card work.

Fuelled by this HTML, JS and CSS wizardry, I decided I'd build my own virtual collecting card game - which is call Requirement5. You discover cards, and collect our in game currency as you do so. If you want to save a card or create your own card, it costs currency. If you create a card and others save it, you get 70% of the currency back. A few friends and I have seeded it with our own creations (helped by the fact we have a CLI, so coding agents can do their bit).

Our lore is about an interplanetary need for earth to express imagination: https://requirement5.com/about
