13. Never Having The Perfect Balance Of Health And Ammo
Even after your RIG is fully upgraded, there will never be enough inventory space for all the items you need. Of course you need four or five health kits in case of emergency, but how much room does that leave for your pulse rifle, plasma cutter, force gun, and contact beam ammunition? If you have enough ammo, you shouldn't need any health kits if you're playing properly, right? You can't use up all your inventory slots though, you need room for schematics and semiconductors! Why can't this game just have inventory Tetris?
