Voice Acting?

I don't think voice acting is a good idea.  Unless you've got a decent set-up and some people with actual like, i dunno theatrical talent, the voice acting thing could get real old real quick. The thought of some whiny kid narrating everything with a scratchy mic gives me goosebumps. 
If your gonna do it, make it professional.

and thus i refer to my earlier statement

Raid the nearest Drama group!

I'm a part of a large drama group at my school...we do improvisation, stage combat, and scripted plays...I could probably hire some of them.

and their equipment too!

They tend to have good Mic's, recorders and stuff.

You know what would be great?  narrating a game with a computer voice, like the ones where you type stuff in and it program says the out loud.

"The. Story. LINE. Has. Progressed. If you would like to continue, please press 1. To pause the game, press 2."

To walk forward, press 8.

If you want to screw yourself and go back to internet explorer press Alt+F4 once you open I.E. that is.

I don't think that would be a good idea. Perhaps having a general voice of the lead character?
