points out that within its first week of availability, Capcom's 'prequel' to Dead Rising 2, DR2: Case Zero
, which is exclusive to Xbox Live, has attracted more than 300,000 users.
The game pretty much plays exactly like a demo, however, everything you do within the game, to a certain point, transfers across to Dead Rising 2 (carried over PP for example). But there are also Achievements to unlock and multiple ways to play through. It's suggested though, that the strong response to this could be a caveat for other publishers offering paid demos on Xbox Live or the PlayStation Network if they had actual gameplay incentives attached (such as Trophies or Achievements), and while Case Zero really won't set you back that much (400 MS Points - AU$6.60), it presents an interesting case.
Have you checked it out yet? Would you pay for a demo if it offered gameplay incentives or even exclusive features the full game won't?
