games on the xbox 360

the games on my xbox 360 are great! but i only have 2!!!! i have tomb raider legend I've completed round about 40 percent of the game i also have xbox live with uno,feeding frenzy...
i bought a hardrive the other day and downloaded pure,race driver grid,cars,ace combat 6,hawk's...i keep it in my brother's room because i don't have any space in my room because of all the other consoles in there ! my favorite game is pure and then race driver grid i always come 1 in pure it's brilliant!!!!!!
