Does anyone else feel like game recommendation engines are completely useless if you play older games?

Every time I use Steam's discovery queue or any "what to play next" site, I get bombarded with stuff from the last 6 months. I get it - that's what generates clicks and sales - but it's genuinely unhelpful for how most of us here actually want to play.

I've been quietly working on a tool to change that. The core idea - your taste doesn't have an expiration date, so recommendations shouldn't either. Something from 2011 that fits exactly what you're looking for should surface just as easily as a 2024 release.

It's early and rough around the edges, but I'm at the point where I want to validate whether this is even a problem worth solving for other people or just a me.

If a recommendation algorithm for games like this existed - smarter discovery that actually respects older games - would you use it?

What features would make it genuinely useful vs just another thing you try once and forget about? I want it to be the tool someone actually recommends to a friend, not just upvotes and forgets.
