anyway wherever the next game takes place there should be a few more guilds..........
1 a vampire guild
2werewolf guild
3a vampire/werewolf/monster hunting guild
..... these guilds should have story lines and missions and all be fighting with one another so you can only join one with the same character also they should be "secret" guilds like the dark brotherhood in oblivion
you should also be able to start a family and own shops and other buildings and rent them to make more money like Fable.......
thats all my ideas for now but im sure il have more
