10 Ways Players Accidentally Broke Video Games
4. Selling Your Stuff - Champions Of Norrath
RPGs have always been largely about organisation. Sorting all your characters to have abilities that fit in with the rest of the team, making sure you're equipment is tip-top, and just generally optimising everything you can is basically RPG 101.
As much as most players desperately hate it, inventory management is very much a part of this. Making sure you have room for more drops and remembering to sell what you don't want to keep is vital for a whole lot of these games, not to mention the lion's share of most MMOs.
And so it's especially cruel that Champions of Norrath punishes you for this, even if it does appear to be by total accident. After killing the suitably unnerving Spider Queen Sheloth, players who've remembered their teleport can quickly pop back to sell all the gross spider goodies she dropped, likely feeling pretty good about themselves for being to prepared.
Only, when they try return to her boss area, they'll soon realise the key issue with this; the boss room is locked. Since an NPC opens this area for you, you're unable to unlock this door yourself, meaning it's time to do another RPG classic manoeuvre of desperately looking through older save files to figure out which you can use to restart.
