What are the file sizes of some of the popular xbox live titles for the windows 7 phones?

I would like to know about how big some of the file sizes are for games like ilomilo, Rocket Riot, Hydro Thunder GO, and some of the more popular games for the windows 7 phones. I want to know because I just ordered an HTC Surround and I know it only has 16 GB of flash memory and it is non-upgradeable. (No Micro-SD slot, which is sort of lame in my opinion but whatever) I want to know about how many of these games I would be able to put on there while still having enough room for other things. (Video, Photos, Music, Other Apps) Thank you!
