The first half of 2017 was filled with amazing games (Yakuza, NiOh, Nier, Persona 5) but we can all agree that they were quite niche and tracking their sales wasn't quite exciting. The only big games were The Legend of Zelda: Breath of the Wild, Mario Kart 8 Deluxe and Horizon: Zero Dawn.
For 2018 it seems the whole year is going to be filled with blockbuster games. Propably starting with REmake 2 (release 21 january for it's 20th anniversary), Far Cry 5 (february), God of War (march), Spider-man (june), RDR2 (august) and the typical holiday titles for the rest of the year.
Finally an excicting first half of the year. SO MUCH SOFTWARE!
