not sure if its my favorite...but lineage 2 is great ryona game...
The dark elves wears very skimpy outfit and have very big breasts, which i admit something i really like. When they die in the water, they arch their backs upward, which is nice given their big boobs.
The light elves/humans, while their boobs arent as big, they have nice thighs, and many of their outfits include a very short skirt. Pretty much can get a very nice upskirt view wen they walking, lying on the ground dead, or wen theyre swimming. As a bonus, when the human dies in the water, she sorta bend forward, doggy style so its a pretty nice upskirt. Both big boobs and upskirt shots are my thing, that prolly why i like the game for ryona.
