A year in which a StarCraft game is released is going to be an easy one to predict my favourite game in. That sounds like the most egregious form of pre-awarding imaginable (and I suppose now’s the time to mention I haven’t played The Witcher 3 yet), but when a company so constantly puts out games of the quality that Blizzard does - and they’re in the midst of making sequels to a game I grew up with as the only ones doing real, big-budget work in that genre at all - it’s kinda inevitable.
There are other strategy games, of course, but they aren't as good.
