Looking for New Game to Buy

I was wondering what is worth getting that I don't already have, here is what I do have:

R6V

Gears Of War

Oblivion

Dead Rising

Marvel Ultimate Alliance

Tiger Woods 07

I have played GRAW and didn't like it that much so not really sure if GRAW2 has done anything more that would change my mind on it.  Also I have seen  Top Spin 2 for 19.99 and Viva Pinata for 29.99.  Are any of these worth it at those prices.

If you like GTA, you will like Saints row. :)

Well sounds like Viva Pinata is the game to go with any other suggestions?

If you're looking for some nice Xbox Live action, go for COD3 or FEAR. Both of them are great options.

I havn't played Viva Piñata yet, but the general opinion is that is a game full of fun and stuff to do and designed for all ages, not only for kids, despite of its appearance.

First of all, he has Rainbow Six and Oblivion already!!

I would recommend Saint's Row, Dead Rising (Both of these take a very long time to complete)

I have not played Viva Pinata so I can't comment on that one.
