The only game I can think of that I played wrongly is Kal Online. This was my first MMO, and the only previous RPG experience I had was with Morrowind. Whenever I get stuck in Morrowind's geometry I can usually drop enough stuff to allow my character to become agile enough to get unstuck by spamming the jump button. I got stuck in Kal, so I tried this. Not only did it not have an encumbrance system, but it didn't even have a jump button. All the items I dropped spawned out of my reach, and I lost all my gear because of passersby just taking them since I was stuck. I was only able to get unstuck by typing the /suicide command and respawning.
