For Xbox players based on the Achievements in Oblivion the game would make references to your character talking about how he or she did something.
Eeew, no thank you please.
Now for the last part Lychans, I loved Vamper ism i never saw it as a disease i saw it as a gift so i to see myself as half a vampire and a werewolf.
Yeah, there was a poll around here somewhere a while back about what should happen if you catch Porphyric Hemophilia and Lycanthropy at the same time. I think the winning options were all variants on "whichever disease incubates first takes over and kills off the other virus," ranging up to "having either disease complete incubation while infected with both = instant painful death." I'd say it's extremely likely that they'll somehow limit you to one or the other at any given time.
