The Xbox LIVE Games on Demand service has just been plumped up once again with the addition of three titles you may just be interested in – while Western gamers get Resident Evil 5 and Beautiful Katamari, Japanese Xbox 360 gamers now have access to Viva Piñata: Party Animals through the service.

Let’s take a walk down memory lane, you and I, with some classic trailers and in-game footage from each of these games, with some accompanying explanatory information to bring you back up to speed, and inform you why you need to part with your hard earned Space Bucks to download these titles.

Let’s start with Resident Evil 5:

“The Resident Evil series continues with this highly anticipated sequel. Searing heat from the merciless sun scorches the earth, while a new evil draws closer.”
