I've tried to play SH5 some times, but couldn't find atmosphere similar to SHIII/GWX, even in small part (this game, apart of graphic, is one big mistake for me). On the opposed side SHIII/GWX has, unfortunately, outdated graphic (very important thing in all kinds of simulators). Only choice is, basing on lurker's OM/OMEGU, try to make megamod compared to GWX, but with better graphic. I hope you guys do it as well as you can
