Here's another one of those games you've just got to play, a game that will probably take the hours away of your normal life as you just can't put the game down. And that game is VHS Story by Dartius which has you tasked with developing your character to be the ultimate fighter. Think of it as The Sims mixed with Rambo as every bit of training takes more of your stamina and hunger. The harder you train the more you'll want to sleep and of cause eat. But it is down to you to how far your character goes in life, will he sit around and be a couch potato or be rich with glory? Just be careful not to push your character too far, you wouldn't want him collapsed with a heavy weight down upon his chest.
VHS Story is also a highly detailed game with retro inspired graphical detail, which would probably suit being on the Amiga. From details such as the cup on the table, to the fridge and weights in the garage. The only down side to the game is it's in PRE-Alpha, but there is an online playable version for you to play and the developers have mentioned Steam Greenlight for summer.
So what are you waiting for? Give it a go!
