Here's one that ticked me off. Sierra's Babylon 5 game. Yes the TV show had horrific acting, but the storyline was great as were the special effects. I'm part of a dying breed that loves space combat sims. Tie-Fighter, Wing Commander, in that order. I even have a retail-shrink wrapped copy of the original X-wing which is worth absolutely nothing. So as you can tell, I love space combat sims and couldn't wait for this game. The inertial control system looked like a much needed (and overlooked) aspect of space combat sims.
Then Sierra canceled it.
Fortunately you can download a similiar title called I Found Her. It's fun, and features that spiffy inertial control system. It's also tough to fly.
