Oh. In that case it becomes a lot simpler. Yes, SH5 is very playable these days, and has been for a couple of years. There are many mods that help make it so, and players with SH5 experience will tell you a lot more than I can, but these days it boils down to one supermod, highly praised by pretty much everyone.
