There are a bunch of titles coming out for PC next year, which certainly means that platform is not done yet (and for that I am grateful)! This is my opinion on what the Top 5 are and there were some tough choices to leave off, like Metro: Last Light and Bioshock Infinite. What are your Top 5?
Assuming we're not adding Dead Linger to the list, even though I expect we'll probably be seeing the Beta release, if not the Final release, in 2013.
Survarium
Arma 3
DayZ standalone
Company of Heroes 3
Firefall
Others:
Starcraft 2 Heart of the Swarm
ArcheAge
Metro Last Light
Crysis 3
Warhammer 40,000: Dark Millennium
Command & Conquer: Generals 2
Rome 2 Total War
Here a few more worth looking at:
Watch Dogs
Dead Space 3
Command & Conquer: Generals 2
That game will fucking SHINE on the PC.
