Which game should I play first?
Definitely, play them in order. 1 hasn't aged the best, but if you're finding it too annoying you can drop it to easy difficulty and still get the story. If you want to know what's going on, watch the cut scenes for 1 and 2. It's still fun even though 3 is not as good as 2 and 4. [Apr 10, 2018]
