god no, keep unreal engine away from this series. not only does it perform worse than my dead grandmother, art in games made in unreal engine are almost universally crap. sfv looked like dried turd and not soft, t7 looked like glossy turd laced with gold and not soft, gg was the only one without an eye cancer inducing artstyle and it's thanks to it being was stylized to hell and back and once again, it's not soft
KT was capable of building very good engines for themselves. they should continue doing their thing instead of mindlessly jumping on the UE wagon
