I had a blast playing the Czech-localized version of Bioscopia until the CD got scratched and it started crashing. I was terrible at gaming (still am but can look up guides now) so I never got past the starting area and reception. Still, the interactive encyclopedia kept working and I went through most of it. I recently pirated a working English-language copy (developed by Tivola together with the German one, I think) and had a blast. It would still crash at later points but I was able to hack the required items in through the plaintext XML save file, as well as 99 credit on the keycard (not as interested in biology anymore) and finish the game.
