Welcome to the forum. If you head over to the download section, or use the search on the top right you will be able to find a lot of games here. To crack with steam is as simple as placing gcf in steamapps folder (in steam installation directory) or ncf in steamapps folder and game files in the common folder. I have no idea about 360 games but I would think it was as simple as flashing the 360 and placing games in the hard disk. About hackers we have very few, moderators and admins here are quick to deal with such people so no need to worry
