Hmmmm, the anime I have seen is all early to mid 90s stuff, but I enjoyed them all.
Bubble Gum Crisis. - Really liked this short series. Was hoping more were to come... really surprised the motorcycles they drove have not been made in real life yet. Thought they were awesome.
Dominion Tank Police - Police with tanks, different.
Ninja Scroll - You know, awesome ninja stuff...
Dirty Pair - Police? detectives or some such that always managed to screw things up real bad. Innuendo all over the place...
Driver? (unsure of the name) - Hmm, All I remember was the guy drove an awesome car all over Chicago, IL even lower Wacker, which is easily identified in the show. As far as I know, it's the only anime that takes place in Chicago, IL. Someone can correct the title if they know the show I'm talking about.
Appleseed - Mecha stuff. I vaguely remember it, but I liked it.
Fist of the North - meh, it was just okay, despite the hype about it at the time.
I completely forget the name, but it takes place in WWII where there are BIG internal combustion engine (think bomber engines, which can be clearly seen) mechs used on the Axis and Allied sides. I do remember the one of the bad guys/girls having a Broomhandle pistol though. The mechs were moved around on flatbed train cars before deployment. I'm sure someone will identify the title that I am forgetting.
