@beehaw.orgI see a lot of recommendations here, but here's a couple that are off the track.
Sound! Euphonium
Silver Spoon
Terror in Resonance
Planetes
Texhnolyze
Kinos Journey - both series are great the 2nd is more like the original source
Mushishi
If the game has any way to trade, it's possible to buy power. Wow Classic or Guild Wars 2 are probably your only really options.
