Funny you should mention Galaga - I've got one of those machines just a few minutes walk from my apartment (comes with Pacman, too). I was never great enough to get the high score in it in the arcade, but I love flying games (they don't make them like they used to, either). What was the one I was obsessed with a decade or 2 ago? Grandia 3 or something? I gotta look into finding out if any of those are still around.
Anyway, thanks for the comment. I think I'm finding my voice here, thanks to comments like these.
