newbie q. - what to do with a game archived in ISO's

Hi, this might seem a dumb question, but it's the first time I've come across a game, in this case, Doom3, its archived in about 30 rar archives, each seemingly with an ISO of 1.5gb?!
I'm assuming somehow you burn the lot onto a DVD and then use the DVD, but I'm at a loss as to exactly how to do this.....
I'm usually good with computers, but this is completely new to me.
Thanks for any help.

 

he he...

doubt anyone here will tell you since you didn't go out and buy the game...

 

LOL, ok fair enough, I guessed that somehow, but it's not my fault I'm a completely skint student needing to play Doom 3
If it's any consolation I'll definitely be buying the XBox version, but I can't wait till next year, lol

 

use winrar to extract .rar files. i personaly use nero to burn cd images.

 

Try a program called daemon tools, when i backup the games i have bough to iso files lets me mount them as if its a cd in drive. saves me time from finding cds.
also handy with my dvd burner. 4 ISOs on a disk. copy whichever i need to HDD mount it and delete when done
