JA2 was one of my first gaming experiences and it is still one of the best games out there. JA2:UB is (in my opinion) the best balanced game of the whole series. Well it is rather short but it really kicks ass if you like strategy games and hate first person shoot-em-up stuff.
Playing it on my Vista PC really makes me happy. I tried to get the gold version working but I had no chance without the old original UB disk. Unfortunately that disk broke yeeeeeaaaars ago.
...and then I found gog.com and a "Vista-ready" downloadable version of one of my all time favourite games.
