I own every Shin Megami Tensei release in NA and some imports.
It's a very low key game series with a dedicated community and known for its quality and difficulty.
Now they don't technically state what kind of game this is, so it could be a fighting game, a Mario Party style game, or a Kart Racer.
Shin Megami Tensei is known for it's contemporary Japanese setting. Usually set in modern Japan and uses a lot of Japanese mythology as well as taking Lovecraftian Lore and Christian beliefs into it.
