Remember Sokpop Collective, those wacky indies who make multiple small games a month? Well, they’ve just released their entire back catalog on Steam. That’s 48 new games in a single day. That’s not actually very impressive, because all the games were already finished. What is actually very impressive is that the games are full-featured: Achievements, trailers, etc. The games are available as Season bundles at 25% off, individually for $3 each, or in one gigantic bundle for 40% off.
If you’re looking for somewhere to start, I’d recommend somewhat-meta God Game Simmiland or train tycoon Soko Loko. You can check out the official spiel on Sokpop at their website, or go check out their now rather extensive Steam developer page.
