Restricted Area. Guilty pleasure of mine. Basically cyberpunk Diablo 2 with a 5 dollar budget, which is why it was released halfway finished. In the future, only dweebs wear body armour, so there's no armour drops. Instead, spawns drop cyberware or bioware, prosthetic arms of meat or metal, instantly insertable eyes, plug-and-play hearts, which you can swap around like you would equipment pieces in Diablo. Every item in the game is a "set" item, based on which manufacturer made it, and equipping several from the same company grants stat bonuses, making hunting for that Oxygenetic cyberleg or artificial armour plated skin a priority.
There are a pitiful 8 or so weapon types (katana, ninja claws, pistol, shotgun, machine gun, plasma rifle and flamer) with differing stats. The good part is that each weapon or item can be upgraded for cash, meaning that you really NEED to do a couple optional sidequest dungeons to raise the money to improve your shotty to deal with the notoriously poorly balanced late-game enemies. Money never becomes pointless, a huge flaw of 95% of the endgame of most RPGs.
I highly recommend Restricted Area. It has a lot of neat ideas and would probably have been one of the greatest games of the early 21st century if it hadn't been for budget constraints and a very low-level and undermanned dev team.
