Heat Signature was amazing, but I never hear anyone talk about it. Thronebreaker: the witcher tales was also really good. The "game" part is so/so, but the interactive storytelling is incredible. Massive Chalice is good if you like XCOM, and the sound track is sick.
Also, it's kind popular, I'll throw out armored core 4. It was my favorite in the series. Great music, great style, and unlike the previous games, non-clunky combat.
I remember COD2 being excellent. The shooting mechanics and graphics felt so gritty and realistic when it came out.
