Tell me the genre.

Help to understand how to find similar music to the one that in these games.
I think that music in games
Diablo 1,2,3;
3/4 The elder scrolls morrowind/oblivion;
Fable the lost chapters;
Gothic 1/2;
Can be attributed to the genre simonenkos, or am I wrong? If it's symphonic music how can you call industry such creations? I tried listening to music on Wikipedia about symphoniously music, rhapsodies, overtures, and Capriccio, etc. but for the soul takes. I trust in your help of the above-described music games like this but how to search?
