If you can brave the sudden exponential expansion of the “Wow JB! You’ve Done It Again!” stickers on everything, JB Hi-Gi at Macquarie Centre has a bunch cheap Xbox 360 games:

Table Tennis – $AUD 62

Quake 4, Ghost Recon Advanced Warfighter, Call of Duty 2, Dynasty Warriors 5,  – each $79. (30-odd bucks off)

I can personally recommend GRAW, and critics tend to agree it’s one of the very best Xbox 360 titles available. 

CoD2 got very favourable reviews too.

So, two of the best 360 games so far, $80 a piece.
