Morrowind 3DS sounds about right to me. A little downgrade of textures, simplify character models a bit, reduce the doodads, maybe a little less draw distance, and then just add enough graphical and lighting tweaks, and we're good to go.
Maybe a third-person MOBA game, but that genre is generally very stressful and is prone to give players some pretty colorful language (very likely Russian words, too). Doesn't have to be too graphically impressive in terms of character and map complexity, but as long as the engine is robust enough to support 5v5 online, at least 40fps, and around 20 characters with room for DLC stuff, it should be awesome.
Other than those, probably a proper 4X game with full features, and maybe a space simulation game like the X series.
