I don't know what to write, so here are some recommendations for underrated games:

YS Orgin: Classic gameplay, amazing soundtrack.

Exceed 3rd Jade Penetrate Black Package: Hilarious title name. Amazing soundtrack.

Revolver 360 Reactor: Practically unbeatable but awesome blue visuals and cool soundtrack. (Free with game.)

Blood Dragon: The ultimate 80's Sci-Fi spoof.
Does not require Far Cry 3 to play.

Savant Ascent: Awesome catchy music, addictive, cheaper than chips.

Metal Gear Rising: Better story than MGSV. Why? "Nanomachines, Son!"
