Super Dimensional Cavalry Southern Cross was used by Carl Macek to splice into Robotech (as the second series, "The Robotech Masters"), which is why I wanted to have it on DVD. Now I have all three series in their original (non-Macek) form. Yes, they're old, and it shows. But the series themselves are still pretty good with respect to plot and the action.
The Macross franchise is still going strong (last year saw the release of Macross Frontier), but the other two have sort of fallen by the wayside. I'd love to see a remake of these series with modern CGI. I think they'd look great, and the plot could be polished up a bit too because of the increased possibilities to show stuff in animation.
Every time I see a mecha show like that, I itch to do an RPG campaign based on such a series. I think it would be fun to have a small group of players and play in a 'military light' campaign. But who would be interested? And would Mekton Zeta or Big Eyes, Small Mouth be better for mecha RPG?
