PS Store questions

I'm curious, is there any difference between the Tekken 5: DR in the US store and the European store? Cause it seems like it's a bit cheaper and you know just so i know for any future games.

Also what would happen if my PS3 breaks down and I've bought a bunch of games from PS Store. Will I loose them or will I be able to download them again? Can I back the games up on a seperate disc or something?

Tekken is the same in both stores. Wait a few weeks (If in the US) and download it with the online mode it will save you a couple bucks.

Also if you need to redownload anything there is a downloads tab in the top right corner of the PS store and you can redownload anything from there if you need to as long as your on the account they were purchased on.
