One of the problems that has existed since around 1982 (when Wizardry 2 was released) has been the issue of dealing with sequels and character power. Wizardry 2 was the first commercial CRPG I can think of that allowed you to move characters over from a previous game, but it was far from the only one. The problem is that your characters at the end of one game are usually pretty freaking buff, with killer gear and stuff. So what does the sequel offer when your character is already level 1 billion, and wields the Awesome Sword of Awesomeness? Up the level cap to a trillion and provide an Even Awesomer Sword of Epic Awesomeness? Do you drop the player's characters level down to a capped point and strip them of their best gear? And then what do you do with game three?
