From a read of their wikipedia, it looks like they’ve been consistently on Unreal :) I can imagine they’d have some people who know that program back to front if they still work there! :)

I tried to install unreal, and it was deeply not fun (linux, epic launcher, disk space, other pains), so I’ve never used it. :)

Can’t wait for shader compilation stutter and aa smear!

Snark aside using an engine makes sense, their last game flopped hard and they should be prioritizing getting a successful title out. They’re good enough that I’d expect them to have most of the common pitfalls worked out anyway
