Trade or go rogue!
Space Rogue is very complete game where you will play elements of role, trading, space simulation and adventure. Let's start by the base idea of the game. You're a merchant commanding a spaceship and you will have to trade stuff around different planets. So, you purchase some good at a price on a planet and you must try to sell at a better price in a different planet. Then, when you approach the planet itself you will have to pilot your spaceship in order to land and be able to run those business. You can even talk to other characters and get precious information about what is going on in this dimension. An interesting stuff is the possibility to engage in combat when you are nearby another spaceship. You decide to go rogue and pirate the spaceship (not before a spaceship battle that will test your sim-flying ability) or you let it be and do your honest trades. Depending on your choices your reputation will change, of course! Then, you can even enter in other dimensions by crossing some sort of wormhole portals. Also here, watch out and be a good pilot. Taking in consideration this game was developed in 80s, we must say it's pure gold as it will be still able to entertain you!
