OK, I'm like, totally new to these Forums, so I don't know whether this suggestion has already been made/dismised/flamed.
Anyways, why don't they include an option to copy one of your old KotOR I savegames into part two, so the game could scan for relevant data on "your" Revan and implement it into the game. After all, SL will be the sequel to one of the most successful games since Idontknowwhen, a geme that sold some hojillion copies, and most of the potential buyers of SL are likely to also have part I - and some savegames, I'm sure.
Togther with the questions/summary that are already planned, this would allow for a greater amount of customization, and make the game more of an individual sequel for each player.
That is, if Obsidian are planning to use Revan at all...
And technically/technologically, it doesn't seem like it would be to difficult to pull it off...
