hlhbk: How does Wing commander hold up if you have never played it?
That's actually a tough question, given how most of us that remember them so fondly were blown away by how technologically advanced they were for the time.
Story wise they are still a lot of fun. The FMV in WCIII, which is usually a turn-off for me, is pretty fantastic and really goes a long way in making it more of a story-telling experience than just a video game. You'll genuinely feel loss, excitement, and despair as the story plays out.
In all honesty, the graphics and gameplay mechanics of the space battles themselves have not held up as well, especially when compared to the X and FreeSpace series (among others), but the immersive story, in my opinion, more than makes up for their technical limitations.
