I'll expand. The characters are going on a quest for the Latin Emperor of Constantinople (the Franco-Venetian puppet) to recover the grail so they can win the next crusade. The problems with the character were as follows:S'mon said:I genuinely don't see what the problem is here?
Edit: except 'having to force into party' - that is certainly a problem, but hardly a cross-gender one. Players obviously need to create PCs who can operate alongside the other PCs.
1. She was not believably female.
2. She was a shallow charicature of feminity.
3. She had a bunch of modern feminist ideas that didn't fit with the setting. (That's not to say medieval women couldn't be unhappy with their roles in society; it's just that their dissatisfaction was not expressed through the prism of modern feminism.)
4. She was incompatible with the party's basis of unity.
5. She constantly transgressed all existing social protocols forcing the other characters to behave in a totally ahistorical way just to interact with her.
She couldn't even survive the introductory speech by the lead NPC in the first scene when the characters were told why they had been brought together without interrupting the nobleman giving it and threatening to quit if he didn't start treating her in the same ahistorical way she was forcing the other PCs to behave.
Basically, the character was a combination of Crothian's problem #2 and problem #3.
In other words, he not only screwed up his character but to use an Einsteinian physics metaphor, he deformed the space around him. This was an historical game; it essentially began with an extortionate demand that people cease behaving historically or the player would walk. The character had problems with medieval gender roles so the player made these difficulties everybody's problems. Fortunately, in the cold light of day, the player realized that the group was not for him and I commend him on that realization.
