Operation: Frog

DOS, Apple II, Commodore 64 1992

Operation Frog is an educational title in which players explore the inside of a frog's body. You can choose between a male frog and a female frog in the reference section. There are two game modes: Dissection and Reconstruction. In Dissection mode, players have to open the frog's body and remove its organs; and in Reconstruction mode, players have to put the already removed organs back into the frog's body in the correct order. This game provides you with scissors, a probe, a magnifying glass and tweezers, the necessary tools for your work. The scissors (not available in the Rebuild section) help you cut the frog's body and remove the organs, the probe gives you hints on where to cut (in the Dissect section) or which part to place first (in the Rebuild section), the magnifying glass gives you information about each organ and the tweezers help you move the organs. You don't have to remove all the organs to see their information, as you can search for them at any time in the Frog File Index section. You can also see the arrangement of the organs in the OptiFrog section. The game offers players a save function.

Trains

DOS, Atari 8-bit, Commodore 64 1983

Trains, released in 1983, is a classic DOS game that has stood the test of time. Developed by Chris Lawson and published by American publisher Dynacomp, this train simulation game provided players with a unique and challenging experience that kept them hooked for hours on end. The concept of the game is simple - players are in charge of managing a train company, from building tracks and managing finances to scheduling routes and delivering goods. The early 1980s was a time when simulation games were gaining popularity, and Trains was one of the pioneers in this genre. Despite its simple premise, the game was surprisingly complex, with many different factors to consider for successful gameplay. One of the most distinctive of Trains was its graphics, which, while rudimentary by today's standards, were impressive for its time. With its isometric view, players could view their trains and the landscapes they traveled through in a three-dimensional space. The game also utilized a colorful and detailed interface that added to the overall experience. The gameplay of Trains was also highly addictive and challenging. Players had to manage their finances carefully, as building tracks and purchasing trains required a significant investment. Route planning was also essential, as delivering goods to cities with high demand could earn a substantial profit. However, managing the delicate balance of resources while ensuring timely deliveries was no easy feat and required strategic thinking and quick reflexes. One of the unique aspects of Trains was its emphasis on realism. The game incorporated various factors such as terrain, weather, and train maintenance that affected gameplay. For example, steep inclines would slow down trains, and harsh weather conditions could lead to delays. These added challenges kept the game from becoming repetitive and added to the overall immersive experience. Trains was also a pioneer in its use of sound effects. While most DOS games of its time had minimal sound, Trains utilized a variety of sounds to create a sense of realism. The whirring of trains, the chugging of engines, and the clanging of bells all added to the overall ambiance and made players feel like true train drivers. Despite its age, Trains continues to have a devoted fanbase, with many still playing the original game or its various remakes. Its success paved the way for many other simulation games, and its impact can still be felt in the genre today. Trains was a true gem of its time, and its legacy continues to live on, making it a must-try for any retro gaming enthusiast.
