An honorable mention goes out to Company of Heroes. Medal of Honor and Call of Duty may have occupied the shooter genre, but Company of Heroes made its mark in the real-time strategy genre.
Known for its gameplay mechanics that are both in-depth and addictive, the first Company of Heroes was often cited as one of the best RTS games of its time and received numerous awards and acclaims. While a sequel was released in 2013, plenty of fans and reviewers felt that Company of Heroes 2 was more of expansion rather than a full-fledged sequel.
Hopefully, the renewed interest in World War II games would entice Relic Entertainment to churn out another Company of Heroes.
