Content types

I would also like to see some variation in content, besides rooms and buldings. FPS’s are cool n all, but i’d like to see more open and expansive environments. things that show off the various types of projects that UE4 can handle. Space sims/shooters, RTS’s, paging terrain, speedtree, volumetric clouds etc etc… i realize that there are things still needing to be done in the engine, but to be honest, i’m still a bit unclear as to what’s available now vs what’s to be added. is there a roadmap of planned features?
