Summary
Science fiction games,specifically space-sims, and RPGs, tend to feature a variety of systems and activities for players to engage in. Sandbox RPGs such asFreelancer, allow players to earn extra cash by mining, salvaging, and trading goods in and between various locations.
These gameplay systems force players to move around the game’s world, keeping the pace and ensuring players are always seeing and interacting with new things. Trading in RPGs can sometimes be as simple as buying and selling items for a flat price, but a great number of sci-fi space-sims and RPGs take things to the next level with simulated economies and black markets.

A Swashbuckling RPG With Accessible Trading
Rebel Galaxyis a unique sci-fi RPG for many reasons. For starters, the game featuresa distinctive combat systemthat focuses on broadside attacks, heavily reminiscent of naval combat. As well as this, the game features a Wild West-inspired space setting that’s comparable to classic sci-fi television shows such asFirefly. This is especially so in the game’s excellent original soundtrack.
Rebel Galaxymay be combat-heavy, with plenty of missions requiring players to shoot up a variety of enemies, but trading is a core part of its gameplay loop. This is especially so for players who want to earn a little extra cash. Thankfully, the game’s trading mechanics are solid, allowing players to easily tell whether or not they’re making a profit when they buy and sell cargo.
