My first character in any game(where you can create a character) is always a wizard/mage. I am also partial to playing a cleric. I do dabble with the other classes, but that is usually after that fact that I've finished the game already with my wizard.
That said, I do believe that the wizards-robes you get in most games are ridiculous, which is sad. I remember playing Dragon Age 2, and my wizard ran around in a spiffy pale-pink number through a lot of the game. Sure, at moments I felt like the dude, but most of the time it just seemed silly.
Skyrim on the other hand have kinda cool, if a little boring, wizards-robes.
Oh, and If I could, I would totally play any modern shooter as a wizard, that would be AWESOME!
