Man, I love this board game with Monopoly/Great Race themes. Made by Blue Byte. Released in 1995-1997 (I don't remember the exact year). This game should be released on GOG, because currently it can only be found on abandonware websites and doesn't work well with current opecating systems.

Here's few game videos:

Looks cool, and I think GOG needs more puzzle games etc.

The dialogue in the first video is hilarious.

I loved this one. Simply loved it. So yeah, great idea :P

Would love to have dr.drago again ... so much fun to play
