Some advice please?

Well im buying an xbox 360, and i want to get 2 or 3 games for it at start, i have been searching in the games list to find some i like, as for now, i have decided to buy The elder scrolls IV and getting the one with the expansion packs included.

I have also liked FF XI, and Kingdom underfire, but i cant decide another more options of good games.

So i made this topic, for you to recommend me some games that have some of the characteristics of the ones i mentioned, so i can decide on whcih other game i would want to buy.

Also, can anyone tell me the price of Castlevania SOTN for the xbox 360 arcade, i really liked that game on PS1, and im thinking of getting it or wheter or not save the money form one game and get this instead

Any help appreciated, Thaks

games = bioshock, halo 3, mass effect, reserve gta4

bioshock has a great atmosphere very creepy and solid gameplay. not only that but it brings out an amazing story and great graphics

Mass effect is huge if you like oblivion you'll like this. theres like 30 some planets to explore good gameplay and some of the best graphics

halo 3- because its halo 3

Thak you very much for the advice im taking it in count

SOTN is $10.SaintJotun
