Incredibly biased SCP fan here. It has hit or miss voice acting, but overall SCP: Secret Files is a pretty good walking sim SCP game reminiscent of What Remains of Edith Finch. The main storyline had an incredibly rushed and out of place ending, but each of the SCPs got pretty good tales with various visual styles and gameplay mechanics in each of them.
I just hope that the planned DLC is either gonna be pretty cheap, bundled together, or just straight up free, since unless they end up as longer stories I can't see paying that much for any of them individually based off the length of the base game ones.
