Nice reviews. I have an odd fascination for the Vectrex. It was a pretty unique home system for the day.
There was apparently a homebrew version of Time Pilot for Vectrex a few years ago called Vector Pilot. Youtube had some good footage of it.
You might want to chase that one down critic. Looks like it's being sold out of Europe:
Best games for vectrex: Berzerk,Star Trek,Web Wars & minefield.
Anyway, awesome reviews.
