Sorry if this has been covered before.. I did a quick search and didn't find anything here, and I googled my question but see that there are many different opinions. I'm going to be picking up Halo 3: ODST on Boxing Day, and in order to install it to my hard drive I'll need to free up some space (read: delete some games I rarely play anymore). My question is: am I able to delete the games themselves while retaining my saved progress? Or when I delete them will I have to start over if/when I ever pick them up to play again? The general consensus on the net was that when I uninstall them I'll keep my achievements at least.. is that also true? Thanks!
