Aventuras AD. was a spanish company, specialised on text-adventure games. They've released 6 games in the past (La aventura original, El Jabato, La dioza de Cozumel, La aventura espacial, Templos Sagrados, Chichén Itzá) and every of these games - except "La aventura espacial" - was released for the Amiga platform too. Unfortunately all their games were available only in spanish language, so I can't tell you much about the story of their games.
The games from Aventuras AD. were very famous in Spain and sold well, because they weren't 100% real text-adventures. Their games also features some beautiful, good looking graphics which rised the atmosphere a lot, because you always wanted to see which picture was shown next. Especially the graphics from J.A. Darder are real eye-candy!
In 1998 Aventuras AD. went bankrupt, nevertheless if you're interested in more infos about this company, you can visit their website. This website is in spanish only, therefore I can't tell you much, what you'll find there... |
