Rockstar's PS2 version of Grand Theft Auto: Vice City Stories has jumped to the top of the UK all-formats chart, helped by a budget price that has seen sales leap by over 35 per cent in the past week.
With only 200 units between them, the latest port of a PSP title has managed to knock Ubisoft's Ghost Recon Advanced Warfighter 2 off the top spot after only one week, to number two.
Square Enix's Final Fantasy XII for the PS2 also drops one place to number three, with Sega's Sonic and the Secret Rings at number four and EA's Tiger Woods PGA Tour 07 at number five.
RealTime Worlds' new Xbox 360 IP Crackdown sits at number six, just ahead of a re-entry by Atari's Test Drive Unlimited, following a release on PSP and PlayStation 2.
Electronic Arts' FIFA 07 is also bumped down the charts to number eight, with expansion pack The Sims 2: Seasons at number nine and Dr Kawashima's Brain Training at number ten.
This week's new entries are Disney Interactive's Spectrobes for the DS at number 23 and EA's SSX Blur for the Wii at number 28.
