2nd Diabotical. Free price is always good. Although as its pretty retro, I kinda suck at it now. Im still on Battlefield a bit, but then thats only fun if you have a good group, otherwise its pretty miserable.
Destiny 2 going free was a good thing if you haven't tried that before. Mechanically, its great, and shooting feels amazing. However, it gets a bit grindy, but NOWHERE as near to BDO, wow that game is nice until the end game..
