360 Roundup - Feeding Frenzy, Viva Pi�ata, more

Oberon's Feeding Frenzy is the latest addition to Xbox Live Arcade on the 360. Many gamers are balking at the $10 pricetag, though the game's 40 levels and two gameplay modes might just justify it... Possibly a cheap attempt to dance on Sony's misfortune, Microsoft revealed a secret project from its developer Rare entitled Viva Pi�ata - which, with its Saturday morning cartoon tie-in, seems to be Redmond's answer to Pok�mon. Details are scarce, but the idea is that you "keep your Pi�ata happy" as part of a "worldwide community of Pi�ata players"... In addition, there are several new items of note in the 360 Marketplace, including:

• more picture packs for Burnout Revenge ($2 each)
  
• pictures and themes for Battlefield 2: Modern Combat and the St. Patrick's Day holiday ($0.63 to $1.88 each)
  
• game trailers for Ghost Recon Advanced Warfighter, The Outfit, Superman Returns and Top Spin 2 (free)
  
• a demo for Ridge Racer 6 (free)
