So, I played openxcom a bunch 4-5 years ago (I think), and enjoyed it. It felt a lot like the original, but with improvements.
There have obviously been improvements since then, but the difficulty level seems way off to me -- "Beginner" is *much* harder than vanilla X-COM. (Which I have also played a ton.)
No, I'm not being affected by the difficulty bug -- I always played on Beginner, and still do. That's plenty stressful enough. I don't like losing soldiers.
I'm finding the current version more frustrating than fun. Back to the original, I guess, but I wanted to call it out in case you've kind of lost track of it, what with all the grognards playing on superhuman and whatnot.
