What sort of person are you
1. Buy it as soon as it comes out and pay the full price.
2. Wait a few weeks/months until it comes down in price.
I'm the second one I'm afraid. The last game I ever bought on release date was Grand Theft Auto Vice City for £34.99 (PS2).
Now with the Internet the way it is and the amount of competition, I just can't bring myself to pay the release price when I know it will be half the price in a months time.
I wanted the new PRO EVO game for the xbox 360... it's now £24.99 on amazon. I see HALO is less then £30 in some places and with Christmas on it's way the likes of PLAY and HMV will probably be doing DEAL OF THE DAYS... which could see 1-2 month old games for around £17.99.
I think the only games I'd get on RELEASE is Resident Evil 5 and the new Grand Theft Auto.
