Well, the only thing that affect the game I meant.
Of course, the roleplay also have something to do with "your" game, but not with the actual game, if you catch my drift.
I too roleplay a lot, but I generally make up my mind for all the names, like I don't like Druli because he hated me in the first game I played (I think I was given a village that was his when I became a lord), so whenever I roleplay (like actually talk and make up voices for the lords and stuff) he is always on my Bad list.
Falsevor (or whatever) is on my good list, just because I like him, he looks good and I like it that he has a banner with three horseshoes and is a Rhodok Lord, that's basically like General Patton having a Swastika on his uniform or something : )
