The only problem I have in Oblivion is that it's so open, and you can be in all those guilds, that it often doesn't make any sense. I'm not just speaking from a "there's no way you should be able to lead all four guilds at the same time" perspective, but if you do things in a certain order, you'll end up having to steal from yourself in the Thieves Guild questline, which is pretty facepalm worthy, especially when you leave yourself a threatening note not to mess around with the Thieves Guild.
